> 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
