      Description

      Suspected 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..
