--------------------------------------
Summary: Ambari does not update
"dfs.namenode.lifeline.rpc-address" during Namenode move operation
Key: AMBARI-25199
URL: https://issues.apache.org/jira/browse/AMBARI-25199
Project: Ambari
Issue Type: Task
Components: ambari-web
Affects Versions: 2.6.2
Reporter: Attila Magyar
Assignee: Attila Magyar
While performing Namenode (NN) move from one host to another. And if
"dfs.namenode.lifeline.rpc-address" property is set., during the NN move, we
see that the value associated with the property
"dfs.namenode.lifeline.rpc-address" that is being moved is not updated. Hence,
NN would fail to start during restart stage of the NN Move operation.
This can be reproduced as below,
1. Have a HDFS HA cluster.
2. Make sure "dfs.namenode.lifeline.rpc-address" is set for both the NNs.
3. Perform the NN move operation from any NN to new host.
4. Observe NN failure to startup during restart phase
