@sadanjan mallireddy , ZKFC keep monitoring Name node server and keep pinging it after every X seconds interval and check health satus and if it does not find it in good state it works with zookeeper and try to convert another stand by name node to active name node and transition happens. In this case you should check whether due to any network issue or memory issue main name node is going in hang mode.
