When client session expired, leader tried to remove it from session map and
remove its EPHEMERAL znode, for example, /test_znode. This operation succeed on
leader, but at the very same time, network fault happended and not synced to
followers, a new leader election launched. After leader election finished, the
new leader is not the old leader. we found the znode /test_znode still existed
in the followers but not on leader
*Scenario :*
1) Create znode E.g.
{{/rmstore/ZKRMStateRoot/RMAppRoot/application_1449644945944_0001/appattempt_1449644945944_0001_000001}}
2) Delete Znode.
3) Network fault b/w follower and leader machines
4) leader election again and follower became leader.
Now data is not synced with new leader..After this client is not able to same
znode.
