a. ambari-metrics-monitor status b. ambari-metrics-monitor stop (if it is running) c. Check the ambari-metrics-collector/hbase-tmp directroy path in Ambari AMS config d. Move the hbase zk temp directory to somewhere mv /hadoop/journalnode/var/lib/ambari-metrics-collector/hbase-tmp/zookeeper/* /tmp/ams-zookeeper-backup/ e. Restart AMS from the Ambari That should resolve the issue Cheers, Pravat Sutar
