Description

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
