+##################### Elasticsearch Configuration Example #####################
+
+# This file contains an overview of various configuration settings,
+# targeted at operations staff. Application developers should
+# consult the guide at <http://elasticsearch.org/guide>.
+#
+# The installation procedure is covered at
+# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup.html>.
+#
+# Elasticsearch comes with reasonable defaults for most settings,
+# so you can try it out without bothering with configuration.
+#
+# Most of the time, these defaults are just fine for running a production
+# cluster. If you're fine-tuning your cluster, or wondering about the
+# effect of certain configuration option, please _do ask_ on the
+# mailing list or IRC channel [http://elasticsearch.org/community].
+
+# Any element in the configuration can be replaced with environment variables
+# by placing them in ${...} notation. For example:
+#
+# node.rack: ${RACK_ENV_VAR}
+
+# For information on supported formats and syntax for the config file, see
+# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup-configuration.html>
+################################### Cluster ###################################
+
+# Cluster name identifies your cluster for auto-discovery. If you're running
+# multiple clusters on the same network, make sure you're using unique names.
+#
+# cluster.name: elasticsearch
+
+cluster.name: ES_AAI
+
+#################################### Node #####################################
+
+node.name: ES_ONAP
+node.master: true
+node.data: true
+
+
+# Use the Cluster Health API [http://localhost:9200/_cluster/health], the
+# Node Info API [http://localhost:9200/_nodes] or GUI tools
+# such as <http://www.elasticsearch.org/overview/marvel/>,
+# <http://github.com/karmi/elasticsearch-paramedic>,
+# <http://github.com/lukas-vlcek/bigdesk> and
+# <http://mobz.github.com/elasticsearch-head> to inspect the cluster state.
+
+# By default, multiple nodes are allowed to start from the same installation location
+# to disable it, set the following:
+
+node.max_local_storage_nodes: 1
+
+
+#################################### Index ####################################
+# You can set a number of options (such as shard/replica options, mapping
+# or analyzer definitions, translog settings, ...) for indices globally,
+# in this file.
+#
+# Note, that it makes more sense to configure index settings specifically for
+# a certain index, either when creating it or by using the index templates API.
+#
+# See <http://elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules.html> and
+# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/indices-create-index.html>
+# for more information.
+
+# Set the number of shards (splits) of an index (5 by default):
+
+index.number_of_shards: 5
+
+# Set the number of replicas (additional copies) of an index (1 by default):
+
+index.number_of_replicas: 1
+
+# These settings directly affect the performance of index and search operations
+# in your cluster. Assuming you have enough machines to hold shards and
+# replicas, the rule of thumb is:
+#
+# 1. Having more *shards* enhances the _indexing_ performance and allows to
+#    _distribute_ a big index across machines.
+# 2. Having more *replicas* enhances the _search_ performance and improves the
+#    cluster _availability_.
+#
+# The "number_of_shards" is a one-time setting for an index.
+#
+# The "number_of_replicas" can be increased or decreased anytime,
+# by using the Index Update Settings API.
+#
+# Elasticsearch takes care about load balancing, relocating, gathering the
+# results from nodes, etc. Experiment with different settings to fine-tune
+# your setup.
+
+# Use the Index Status API (<http://localhost:9200/A/_status>) to inspect
+# the index status.
+
+
+#################################### Paths ####################################
+
+# Path to directory containing configuration (this file and logging.yml):
+#path.conf: /opt/app/elasticsearch/config
+
+# Path to directory where to store index data allocated for this node.
+# Use swm auto link to redirect the data directory if necessary.
+
+#path.data: /opt/app/elasticsearch/data
+
+# path.data: /path/to/data1,/path/to/data2
+
+# path.work: /path/to/work
+
+#path.logs: /opt/app/elasticsearch/logs
+
+#path.plugins: /opt/app/elasticsearch/plugins
+
+
+#################################### Plugin ###################################
+
+# If a plugin listed here is not installed for current node, the node will not start.
+#
+# plugin.mandatory: mapper-attachments,lang-groovy
+
+
+################################### Memory ####################################
+
+# Elasticsearch performs poorly when JVM starts swapping: you should ensure that
+# it _never_ swaps.
+#
+# Set this property to true to lock the memory: default is true
+
+bootstrap.mlockall: true
+
+# Make sure that the ES_MIN_MEM and ES_MAX_MEM environment variables are set
+# to the same value, and that the machine has enough memory to allocate
+# for Elasticsearch, leaving enough memory for the operating system itself.
+#
+# You should also make sure that the Elasticsearch process is allowed to lock
+# the memory, eg. by using `ulimit -l unlimited`.
+
+
+############################## Network And HTTP ###############################
+# Elasticsearch, by default, binds itself to the 0.0.0.0 address, and listens
+# on port [9200-9300] for HTTP traffic and on port [9300-9400] for node-to-node
+# communication. (the range means that if the port is busy, it will automatically
+# try the next port).
+
+# Set the bind address specifically (IPv4 or IPv6):
+network.bind_host: 0.0.0.0
+
+# Set the address other nodes will use to communicate with this node. If not
+# set, it is automatically derived. It must point to an actual IP address.
+
+# network.publish_host: 0.0.0.0
+
+# Set both 'bind_host' and 'publish_host':
+# network.host: 192.168.0.1
+
+
+# Set a custom port for the node to node communication (9300 by default):
+transport.tcp.port: 8443
+
+# Enable compression for all communication between nodes (disabled by default):
+transport.tcp.compress: false
+
+# Set a custom port to listen for HTTP traffic:
+# http.port: 9200
+http.port: 9200
+
+# Set a custom allowed content length:
+# http.max_content_length: 100mb
+http.max_content_length: 100mb
+
+# Disable HTTP completely:
+# http.enabled: false
+http.enabled: true
+
+# This is specifically useful for permitting which front end Kibana Url's are permitted to access elastic search.
+http.cors.enabled: false
+http.cors.allow-origin: "/.*/"
+http.cors.allow-headers: X-Requested-With, Content-Type, Content-Length
+http.cors.allow-credentials: false
+################################### Gateway ###################################
+
+# The gateway allows for persisting the cluster state between full cluster
+# restarts. Every change to the state (such as adding an index) will be stored
+# in the gateway, and when the cluster starts up for the first time,
+# it will read its state from the gateway.
+# There are several types of gateway implementations. For more information, see
+# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-gateway.html>.
+
+# The default gateway type is the "local" gateway (recommended):
+#
+#gateway.type: local
+#gateway.type: local
+
+# Settings below control how and when to start the initial recovery process on
+# a full cluster restart (to reuse as much local data as possible when using shared
+# gateway).
+
+# Allow recovery process after N nodes in a cluster are up:
+#
+# gateway.recover_after_nodes: 1
+gateway.recover_after_nodes: 1
+
+# Set the timeout to initiate the recovery process, once the N nodes
+# from previous setting are up (accepts time value):
+#
+#gateway.recover_after_time: 5m
+gateway.recover_after_time: 5m
+
+# Set how many nodes are expected in this cluster. Once these N nodes
+# are up (and recover_after_nodes is met), begin recovery process immediately
+# (without waiting for recover_after_time to expire):
+#
+# gateway.expected_nodes: 2
+gateway.expected_nodes: 2
+
+############################# Recovery Throttling #############################
+
+# These settings allow to control the process of shards allocation between
+# nodes during initial recovery, replica allocation, rebalancing,
+# or when adding and removing nodes.
+
+# Set the number of concurrent recoveries happening on a node:
+#
+# 1. During the initial recovery
+#
+# cluster.routing.allocation.node_initial_primaries_recoveries: 4
+#
+# 2. During adding/removing nodes, rebalancing, etc
+#
+# cluster.routing.allocation.node_concurrent_recoveries: 2
+
+# Set to throttle throughput when recovering (eg. 100mb, by default 20mb):
+# indices.recovery.max_bytes_per_sec: 20mb
+indices.recovery.max_bytes_per_sec: 20mb
+
+# Set to limit the number of open concurrent streams when
+# recovering a shard from a peer:
+#
+# indices.recovery.concurrent_streams: 5
+indices.recovery.concurrent_streams: 5
+
+################################## Discovery ##################################
+
+# Discovery infrastructure ensures nodes can be found within a cluster
+# and master node is elected. Multicast discovery is the default.
+
+# Set to ensure a node sees N other master eligible nodes to be considered
+# operational within the cluster. Its recommended to set it to a higher value
+# than 1 when running more than 2 nodes in the cluster.
+#
+discovery.zen.minimum_master_nodes: 1
+
+# Set the time to wait for ping responses from other nodes when discovering.
+# Set this option to a higher value on a slow or congested network
+# to minimize discovery failures:
+#
+# discovery.zen.ping.timeout: 3s
+discovery.zen.ping.timeout:
+
+# For more information, see
+# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-discovery-zen.html>
+
+# Unicast discovery allows to explicitly control which nodes will be used
+# to discover the cluster. It can be used when multicast is not present,
+# or to restrict the cluster communication-wise.
+#
+# 1. Disable multicast discovery (enabled by default):
+# discovery.zen.ping.multicast.enabled: false
+discovery.zen.ping.multicast.enabled: false
+
+
+# 2. Configure an initial list of master nodes in the cluster
+#    to perform discovery when new nodes (master or data) are started:
+#
+# discovery.zen.ping.unicast.hosts: ["host1", "host2:port"]
+discovery.zen.ping.unicast.hosts: ["0.0.0.0"]
+
+# EC2 discovery allows to use AWS EC2 API in order to perform discovery.
+#
+# You have to install the cloud-aws plugin for enabling the EC2 discovery.
+#
+# For more information, see
+# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-discovery-ec2.html>
+#
+#
+# See <http://elasticsearch.org/tutorials/elasticsearch-on-ec2/>
+# for a step-by-step tutorial.
+
+# GCE discovery allows to use Google Compute Engine API in order to perform discovery.
+#
+# You have to install the cloud-gce plugin for enabling the GCE discovery.
+#
+# For more information, see <https://github.com/elasticsearch/elasticsearch-cloud-gce>.
+
+# Azure discovery allows to use Azure API in order to perform discovery.
+#
+# You have to install the cloud-azure plugin for enabling the Azure discovery.
+#
+# For more information, see <https://github.com/elasticsearch/elasticsearch-cloud-azure>.
