Brandon Li resolved HDFS-2811.
------------------------------
Resolution: Invalid
As it was pointed out, the client should not be aware of the block pool ID, and
even it did, the verification on client side is hard to be fool proof. Close it
as not a problem.
> HA: Client should fail if a failover occurs which switches block pool ID
> ------------------------------------------------------------------------

> Components: ha, hdfs client, name-node
> Affects Versions: HA branch (HDFS-1623)
> Reporter: Aaron T. Myers
> Assignee: Brandon Li

> Making sure that the client is talking to an NN with the same block pool ID
> as the one it was previously talking to seems like a good sanity check.
