Don't stop controller on dmaap failure
Modified feature-pooling-dmaap so that it continues to work even if it's unable to communicate with the internal DMaaP topic. When that happens, it simply starts processing locally, until communication is re-established and it receives a bucket assignment. Fixed typo in comment. Added to comment for State.internalTopicFailed(). Removed extra space before @Ignore. Change-Id: I9c851c66c9162c608f2df98e11d49fc526539434 Issue-ID: POLICY-878 Signed-off-by: Jim Hahn <jrh3@att.com>
