-# HDFS charts
-
-Helm charts for launching HDFS daemons in a K8s cluster. The main entry-point
-chart is `hdfs-k8s`, which is a uber-chart that specifies other charts as
-dependency subcharts. This means you can launch all HDFS components using
-`hdfs-k8s`.
-
-Note that the HDFS charts are currently in pre-alpha quality. They are also
-being heavily revised and are subject to change.
-
-HDFS on K8s supports the following features:
-  - namenode high availability (HA): HDFS namenode daemons are in charge of
-    maintaining file system metadata concerning which directories have which
-    files and where are the file data. Namenode crash will cause service outage.
-    HDFS can run two namenodes in active/standby setup. HDFS on K8s supports HA.
-  - K8s persistent volumes (PV) for metadata: Namenode crash will cause service
-    outage. Losing namenode metadata can lead to loss of file system. HDFS on
-    K8s can store the metadata in remote K8s persistent volumes so that metdata
-    can remain intact even if both namenode daemons are lost or restarted.
-  - K8s HostPath volumes for file data: HDFS datanodes daemons store actual
-    file data. File data should also survive datanode crash or restart. HDFS on
-    K8s stores the file data on the local disks of the K8s cluster nodes using
-    K8s HostPath volumes. (We plan to switch to a better mechanism, K8s
-    persistent local volumes)
-  - Kerberos: Vanilla HDFS is not secure. Intruders can easily write custom
-    client code, put a fake user name in requests and steal data. Production
-    HDFS often secure itself using Kerberos. HDFS on K8s supports Kerberos.
-
-Here is the list of all charts.
-
-  - hdfs-k8s: main uber-chart. Launches other charts.
-  - hdfs-namenode-k8s: a statefulset and other K8s components for launching HDFS
-    namenode daemons, which maintains file system metadata. The chart supports
-    namenode high availability (HA).
-  - hdfs-datanode-k8s: a daemonset and other K8s components for launching HDFS
-    datanode daemons, which are responsible for storing file data.
-  - hdfs-config-k8s: a configmap containing Hadoop config files for HDFS.
-  - zookeeper: This chart is NOT in this repo. But hdfs-k8s pulls the zookeeper
-    chart in the incubator remote repo
-    (https://kubernetes-charts-incubator.storage.googleapis.com/)
-    as a dependency and launhces zookeeper daemons. Zookeeper makes sure
-    only one namenode is active in the HA setup, while the other namenode
-    becomes standby. By default, we will launch three zookeeper servers.
-  - hdfs-journalnode-k8s: a statefulset and other K8s components for launching
-    HDFS journalnode quorums, which ensures the file system metadata are
-    properly shared among the two namenode daemons in the HA setup.
-    By default, we will launch three journalnode servers.
-  - hdfs-client-k8s: a pod that is configured to run Hadoop client commands
-    for accessing HDFS.
-  - hdfs-krb5-k8s: a size-1 statefulset and other K8s components for launching
-    a Kerberos server, which can be used to secure HDFS. Disabled by default.
-  - hdfs-simple-namenode-k8s: Disabled by default. A simpler setup of the
-    namenode that launches only one namenode. i.e. This does not support HA. It
-    does not support Kerberos nor persistent volumes either. As it does not
-    support HA, we also don't need zookeeper nor journal nodes.  You may prefer
-    this if you want the simplest possible setup.
-
-# Prerequisite
-
-Requires Kubernetes 1.6+ as the `namenode` and `datanodes` are using
-`ClusterFirstWithHostNet`, which was introduced in Kubernetes 1.6
-
-# Usage
-
-## Basic
-
-The HDFS daemons can be launched using the main `hdfs-k8s` chart. First, build
-the main chart using:
-
-```
-  $ helm repo add incubator  \
-      https://kubernetes-charts-incubator.storage.googleapis.com/
-  $ helm dependency build charts/hdfs-k8s
-```
-
-Zookeeper, journalnodes and namenodes need persistent volumes for storing
-metadata. By default, the helm charts do not set the storage class name for
-dynamically provisioned volumes, nor does it use persistent volume selectors for
-static persistent volumes.
-
-This means it will rely on a provisioner for default storage volume class for
-dynamic volumes. Or if your cluster has statically provisioned volumes, the
-chart will match existing volumes entirely based on the size requirements. To
-override this default behavior, you can specify storage volume classes for
-dynamic volumes, or volume selectors for static volumes. See below for how to
-set these options.
-
-  - namenodes: Each of the two namenodes needs at least a 100 GB volume.  i.e.
-    Yon need two 100 GB volumes. This can be overridden by the
-    `hdfs-namenode-k8s.persistence.size` option.
-    You can also override the storage class or the selector using
-    `hdfs-namenode-k8s.persistence.storageClass`, or
-    `hdfs-namenode-k8s.persistence.selector` respectively. For details, see the
-    values.yaml file inside `hdfs-namenode-k8s` chart dir.
-  - zookeeper: You need three > 5 GB volumes. i.e. Each of the two zookeeper
-    servers will need at least 5 GB in the volume. Can be overridden by
-    the `zookeeper.persistence.size` option. You can also override
-    the storage class using `zookeeper.persistence.storageClass`.
-  - journalnodes: Each of the three journalnodes will need at least 20 GB in
-    the volume. The size can be overridden by the
-    `hdfs-journalnode-k8s.persistence.size` option.
-    You can also override the storage class or the selector using
-    `hdfs-journalnode-k8s.persistence.storageClass`, or
-    `hdfs-journalnode-k8s.persistence.selector` respectively. For details, see the
-    values.yaml file inside `hdfs-journalnode-k8s` chart dir.
-  - kerberos: The single Kerberos server will need at least 20 GB in the volume.
-    The size can be overridden by the `hdfs-krb5-k8s.persistence.size` option.
-    You can also override the storage class or the selector using
-    `hdfs-krb5-k8s.persistence.storageClass`, or
-    `hdfs-krb5-k8s.persistence.selector` respectively. For details, see the
-    values.yaml file inside `hdfs-krb5-k8s` chart dir.
-
-Then launch the main chart. Specify the chart release name say "my-hdfs",
-which will be the prefix of the K8s resource names for the HDFS components.
-
-```
-  $ helm install -n my-hdfs charts/hdfs-k8s
-```
-
-Wait for all daemons to be ready. Note some daemons may restart themselves
-a few times before they become ready.
-
-```
-  $ kubectl get pod -l release=my-hdfs
-
-  NAME                             READY     STATUS    RESTARTS   AGE
-  my-hdfs-client-c749d9f8f-d5pvk   1/1       Running   0          2m

-  my-hdfs-journalnode-2            1/1       Running   0          1m
-  my-hdfs-namenode-0               1/1       Running   3          2m
-  my-hdfs-namenode-1               1/1       Running   3          2m
-  my-hdfs-zookeeper-0              1/1       Running   0          2m
-  my-hdfs-zookeeper-1              1/1       Running   0          2m
-  my-hdfs-zookeeper-2              1/1       Running   0          2m
-```
-
-Namenodes and datanodes are currently using the K8s `hostNetwork` so they can
-see physical IPs of each other. If they are not using `hostNetowrk`,
-overlay K8s network providers such as weave-net may mask the physical IPs,
-which will confuse the data locality later inside namenodes.
-
-Finally, test with the client pod:
-
-```
-  $ _CLIENT=$(kubectl get pods -l app=hdfs-client,release=my-hdfs -o name |  \
-      cut -d/ -f 2)
-  $ kubectl exec $_CLIENT -- hdfs dfsadmin -report
-  $ kubectl exec $_CLIENT -- hdfs haadmin -getServiceState nn0
-  $ kubectl exec $_CLIENT -- hdfs haadmin -getServiceState nn1
-
-  $ kubectl exec $_CLIENT -- hadoop fs -rm -r -f /tmp
-  $ kubectl exec $_CLIENT -- hadoop fs -mkdir /tmp
-  $ kubectl exec $_CLIENT -- sh -c  \
-    "(head -c 100M < /dev/urandom > /tmp/random-100M)"
-  $ kubectl exec $_CLIENT -- hadoop fs -copyFromLocal /tmp/random-100M /tmp
-```
-
-## Kerberos
-
-Kerberos can be enabled by setting a few related options:
-
-```
-  $ helm install -n my-hdfs charts/hdfs-k8s  \
-    --set global.kerberosEnabled=true  \
-    --set global.kerberosRealm=MYCOMPANY.COM  \
-    --set tags.kerberos=true
-```
-
-This will launch all charts including the Kerberos server, which will become
-ready pretty soon. However, HDFS daemon charts will be blocked as the deamons
-require Kerberos service principals to be available. So we need to unblock
-them by creating those principals.
-
-First, create a configmap containing the common Kerberos config file:
-
-```
-  _MY_DIR=~/krb5
-  mkdir -p $_MY_DIR
-  _KDC=$(kubectl get pod -l app=hdfs-krb5,release=my-hdfs --no-headers  \
-      -o name | cut -d/ -f2)
-  _run kubectl cp $_KDC:/etc/krb5.conf $_MY_DIR/tmp/krb5.conf
-  _run kubectl create configmap my-hdfs-krb5-config  \
-    --from-file=$_MY_DIR/tmp/krb5.conf
-```
-
-Second, create the service principals and passwords. Kerberos requires service
-principals to be host specific. Some HDFS daemons are associated with your K8s
-cluster nodes' physical host names say kube-n1.mycompany.com, while others are
-associated with Kubernetes virtual service names, for instance
-my-hdfs-namenode-0.my-hdfs-namenode.default.svc.cluster.local. You can get
-the list of these host names like:
-
-```
-  $ _HOSTS=$(kubectl get nodes  \
-    -o=jsonpath='{.items[*].status.addresses[?(@.type == "Hostname")].address}')
-
-  $ _HOSTS+=$(kubectl describe configmap my-hdfs-config |  \
-      grep -A 1 -e dfs.namenode.rpc-address.hdfs-k8s  \
-          -e dfs.namenode.shared.edits.dir |  
-      grep "<value>" |
-      sed -e "s/<value>//"  \
-          -e "s/<\/value>//"  \
-          -e "s/:8020//"  \
-          -e "s/qjournal:\/\///"  \
-          -e "s/:8485;/ /g"  \
-          -e "s/:8485\/hdfs-k8s//")
-```
-
-Then generate per-host principal accounts and password keytab files.
-
-```
-  $ _SECRET_CMD="kubectl create secret generic my-hdfs-krb5-keytabs"
-  $ for _HOST in $_HOSTS; do
-      kubectl exec $_KDC -- kadmin.local -q  \
-        "addprinc -randkey hdfs/$_HOST@MYCOMPANY.COM"
-      kubectl exec $_KDC -- kadmin.local -q  \
-        "addprinc -randkey HTTP/$_HOST@MYCOMPANY.COM"
-      kubectl exec $_KDC -- kadmin.local -q  \
-        "ktadd -norandkey -k /tmp/$_HOST.keytab hdfs/$_HOST@MYCOMPANY.COM HTTP/$_HOST@MYCOMPANY.COM"
-      kubectl cp $_KDC:/tmp/$_HOST.keytab $_MY_DIR/tmp/$_HOST.keytab
-      _SECRET_CMD+=" --from-file=$_MY_DIR/tmp/$_HOST.keytab"
-    done
-```
-
-The above was building a command using a shell variable `SECRET_CMD` for
-creating a K8s secret that contains all keytab files. Run the command to create
-the secret.
-
-```
-  $ $_SECRET_CMD
-```
-
-This will unblock all HDFS daemon pods. Wait until they become ready.
-
-Finally, test the setup using the following commands:
-
-```
-  $ _NN0=$(kubectl get pods -l app=hdfs-namenode,release=my-hdfs -o name |  \
-      head -1 |  \
-      cut -d/ -f2)
-  $ kubectl exec $_NN0 -- sh -c "(apt install -y krb5-user > /dev/null)"  \
-      || true
-  $ kubectl exec $_NN0 --   \
-      kinit -kt /etc/security/hdfs.keytab  \
-      hdfs/my-hdfs-namenode-0.my-hdfs-namenode.default.svc.cluster.local@MYCOMPANY.COM
-  $ kubectl exec $_NN0 -- hdfs dfsadmin -report
-  $ kubectl exec $_NN0 -- hdfs haadmin -getServiceState nn0
-  $ kubectl exec $_NN0 -- hdfs haadmin -getServiceState nn1
-  $ kubectl exec $_NN0 -- hadoop fs -rm -r -f /tmp
-  $ kubectl exec $_NN0 -- hadoop fs -mkdir /tmp
-  $ kubectl exec $_NN0 -- hadoop fs -chmod 0777 /tmp
-  $ kubectl exec $_KDC -- kadmin.local -q  \
-      "addprinc -randkey user1@MYCOMPANY.COM"
-  $ kubectl exec $_KDC -- kadmin.local -q  \
-      "ktadd -norandkey -k /tmp/user1.keytab user1@MYCOMPANY.COM"
-  $ kubectl cp $_KDC:/tmp/user1.keytab $_MY_DIR/tmp/user1.keytab
-  $ kubectl cp $_MY_DIR/tmp/user1.keytab $_CLIENT:/tmp/user1.keytab
-
-  $ kubectl exec $_CLIENT -- sh -c "(apt install -y krb5-user > /dev/null)"  \
-      || true
-
-  $ kubectl exec $_CLIENT -- kinit -kt /tmp/user1.keytab user1@MYCOMPANY.COM
-  $ kubectl exec $_CLIENT -- sh -c  \
-      "(head -c 100M < /dev/urandom > /tmp/random-100M)"
-  $ kubectl exec $_CLIENT -- hadoop fs -ls /
-  $ kubectl exec $_CLIENT -- hadoop fs -copyFromLocal /tmp/random-100M /tmp
-```
-
-## Advanced options
-
-### Setting HostPath volume locations for datanodes
-
-HDFS on K8s stores the file data on the local disks of the K8s cluster nodes
-using K8s HostPath volumes. You may want to change the default locations. Set
-global.dataNodeHostPath to override the default value. Note the option
-takes a list in case you want to use multiple disks.
-
-```
-  $ helm install -n my-hdfs charts/hdfs-k8s  \
-      --set "global.dataNodeHostPath={/mnt/sda1/hdfs-data0,/mnt/sda1/hdfs-data1}"
-```
-
-### Using an existing zookeeper quorum
-
-By default, HDFS on K8s pulls in the zookeeper chart in the incubator remote
-repo (https://kubernetes-charts-incubator.storage.googleapis.com/) as a
-dependency and launhces zookeeper daemons. But your K8s cluster may already
-have a zookeeper quorum.
-
-It is possible to use the existing zookeeper. We just need set a few options
-in the helm install command line. It should be something like:
-
-```
-  $helm install -n my-hdfs charts/hdfs-k8s  \
-    --set condition.subchart.zookeeper=false  \
-    --set global.zookeeperQuorumOverride=zk-0.zk-svc.default.svc.cluster.local:2181,zk-1.zk-svc.default.svc.cluster.local:2181,zk-2.zk-svc.default.svc.cluster.local:2181
-```
-
-Setting `condition.subchart.zookeeper` to false prevents the uber-chart from
-bringing in zookeeper as sub-chart. And the `global.zookeeperQuorumOverride`
-option specifies the custom address for a zookeeper quorum. Use your
-zookeeper address here.
-
-### Pinning namenodes to specific K8s cluster nodes
-
-Optionally, you can attach labels to some of your k8s cluster nodes so that
-namenodes will always run on those cluster nodes. This can allow your HDFS
-client outside the Kubernetes cluster to expect stable IP addresses. When used
-by those outside clients, Kerberos expects the namenode addresses to be stable.
-
-```
-  $ kubectl label nodes YOUR-HOST-1 hdfs-namenode-selector=hdfs-namenode
-  $ kubectl label nodes YOUR-HOST-2 hdfs-namenode-selector=hdfs-namenode
-```
-
-You should add the nodeSelector option to the helm chart command:
-
-```
-  $ helm install -n my-hdfs charts/hdfs-k8s  \
-     --set hdfs-namenode-k8s.nodeSelector.hdfs-namenode-selector=hdfs-namenode \
-     ...
-```
-
-### Excluding datanodes from some K8s cluster nodes
-
-You may want to exclude some K8s cluster nodes from datanodes launch target.
-For instance, some K8s clusters may let the K8s cluster master node launch
-a datanode. To prevent this, label the cluster nodes with
-`hdfs-datanode-exclude`.
-
-```
-  $ kubectl label node YOUR-CLUSTER-NODE hdfs-datanode-exclude=yes
-```
-
-### Launching with a non-HA namenode
-
-You may want non-HA namenode since it is the simplest possible setup.
-Note this won't launch zookeepers nor journalnodes.
-
-The single namenode is supposed to be pinned to a cluster host using a node
-label.  Attach a label to one of your K8s cluster node.
-
-```
-  $ kubectl label nodes YOUR-CLUSTER-NODE hdfs-namenode-selector=hdfs-namenode-0
-```
-
-The non-HA setup does not even use persistent vlumes. So you don't even
-need to prepare persistent volumes. Instead, it is using hostPath volume
-of the pinned cluster node. So, just launch the chart while
-setting options to turn off HA. You should add the nodeSelector option
-so that the single namenode would find the hostPath volume of the same cluster
-node when the pod restarts.
-
-```
-  $ helm install -n my-hdfs charts/hdfs-k8s  \
-      --set tags.ha=false  \
-      --set tags.simple=true  \
-      --set global.namenodeHAEnabled=false  \
-      --set hdfs-simple-namenode-k8s.nodeSelector.hdfs-namenode-selector=hdfs-namenode-0
-```
-
-# Security
-
-## K8s secret containing Kerberos keytab files
-
-The Kerberos setup creates a K8s secret containing all the keytab files of HDFS
-daemon service princialps. This will be mounted onto HDFS daemon pods. You may
-want to restrict access to this secret using k8s
-[RBAC](https://kubernetes.io/docs/admin/authorization/rbac/), to minimize
-exposure of the keytab files.
-
-## HostPath volumes
-`Datanode` daemons run on every cluster node. They also mount k8s `hostPath`
-local disk volumes.  You may want to restrict access of `hostPath`
-using `pod security policy`.
-See [reference](https://github.com/kubernetes/examples/blob/master/staging/podsecuritypolicy/rbac/README.md))
