----------------------------------------
Summary: AMS: Deleting ZK data in embedded mode results in external phoenix clients unable to connect on AMS restart
Key: AMBARI-17799
URL: https://issues.apache.org/jira/browse/AMBARI-17799
Project: Ambari
Issue Type: Bug
Components: ambari-metrics
Affects Versions: 2.0.0
Reporter: Siddharth Wagle
Assignee: Siddharth Wagle
Priority: Critical
Fix For: 2.4.0
AMS stack script delete ZK data because when standalone HBase restarts, the ZK data quite frequently gets corrupt and the restart is no longer works.
This is because all daemon run inside the same JVM. We had to do this as a workaround after which restart of AMS in embedded mode became reliable
With HBASE-16244, the standalone mode restart will succeed and we do not need to cleanup zookeeper data
