I’ve turned on Namenode HA and Resource HA on a cluster running Ambari 2.1 and HDP 2.2. The resource HA wizard could not complete because the Metrics Collector refuses to restart. From the logs for the Metrics embedded HBase Master, I’m seeing exceptions:
master.HMaster: Unhandled exception. Starting shutdown. org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.ipc.StandbyException): Operation category READ is not supported in state standby It appears the master is trying to use the Namenode that is in standby mode rather than the active Namenode. How can I get the collector to start using the active name node? Thanks Brian
