> 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
