Pivotal command center(PCC) 2.2.1
hadoop-hdfs-zkfc service is installed on active and standby namenode to enable namenode HA auto failover. In PHD 188.8.131.52/PCC 2.2.1, the ICM client doesn't handle service start/stop/restart of hadoop-hdfs-zkfc.
To confirm the problem.
1: Check if hadoop namenode HA is deployed or reconfigured by icm_client. Export cluster configuration by running
icm_client fetch-configuration -l <cluser_ID> -o <output_dir>
If clusterConfig.xml under <output_dir> has contents of the HA namenode configuration, it means hadoop namenode HA was enabled through icm_client deployment or reconfigure.
2: Restart the cluster by running
icm_client restart -l <cluser_ID>
Monitor /var/log/message on admin node, you can see icm restarted other stacks but not hadoop-hdfs-zkfc. Also, from either namenode, you can monitor the hadoop-hdfs-zkfc by running
chkconfig hadoop-hdfs-zkfc on
