Customer has setup a configuration for remote servers which are HA in their
configs.
They started seeing this after making those changes.
dfs.namenode.http-address.nonha=<local-cluster-NN-IP>:50070
dfs.nameservices.internal=nonha
dfs.nameservices=nonha,hacluster
dfs.namenode.rpc-address.nonha=<local-cluster-NN-IP>:8020
dfs.namenode.rpc-address.hacluster.nn2=<remote-cluster-NN1-IP>:8020
dfs.namenode.rpc-address.hacluster.nn1=<remote-cluster-NN2-IP>:8020
dfs.ha.namenodes.hacluster=nn1,nn2
dfs.client.failover.proxy.provider.hacluster=org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider
Basically dfs.ha.namenodes.NNSERVICE value is not defined and it errors out.
