                 Key: HDFS-8161
                 URL: https://issues.apache.org/jira/browse/HDFS-8161

Scenario:
========
Start cluster with three Nodes.
Reboot Machine where ZKFC is not running..( Here Active Node ZKFC should open session with
this ZK )

Now  ZKFC ( Active NN's ) session expire and try re-establish connection with another ZK...Bythe
time  ZKFC ( StndBy NN's ) will try to fence old active and create the active Breadcrumb and
Makes SNN to active state..

But immediately it fence to standby state.. ( Here is the doubt)

Hence both will be in standby state..
