    Description

      We have met such a HA scenario:
      NN1(active) and zkfc1 on node1;
      NN2(standby) and zkfc2 on node2.
      1,Stop network on node1, NN2 becomes active. On node1, zkfc1 kills itself since it cannot connect to zookeeper, but leaving NN1 still running.
      2,Several minutes later, network on node1 recovers. NN1 is running but out of control. NN1 and NN2 both run as active nn.
      Maybe zkfc should stop nn before quit in such circumstances.
