>            Priority: Major

> As per the current design, region server will fail over only if the connection got some exception.
> As described in HBASE-14498, if there is any issue in master instance related to zookeeper connection, the standBy master will become active. But the region servers will not fail over
> This particular issue can be fixed in master side.
> But as a generic solution, i think region server needs to depend on zookeeper watch to identify the master change.
> Assigning to [~pankaj2461] since this work is related to HBASE-14498
> Any thoughts ?
