-------------------------------------------
Very good catch [~arshad.mohammad]! My two cents*:
Other typo:
{code}
Stat firstEphemralNode = new Stat();
{code}
PS: have been absent for a loooong time, coming back now, cheers! :)

> ZooKeeper ephemeral node is never deleted if follower fail while reading the
> proposal packet
> The scenario is as follows:
> # Configure three node ZooKeeper cluster, lets say nodes are A, B and C,
> start all, assume A is leader, B and C are follower
> # Connect to any of the server and create ephemeral node /e1
> # Close the session, ephemeral node /e1 will go for deletion
> # While receiving delete proposal make Follower B to fail with
> {{SocketTimeoutException}}. This we need to do to reproduce the scenario
> otherwise in production environment it happens because of network fault.
> # Remove the fault, just check that faulted Follower is now connected with
> quorum
> # Connect to any of the server, create the same ephemeral node /e1, created
> is success.
> # Close the session, ephemeral node /e1 will go for deletion
> # {color:red}/e1 is not deleted from the faulted Follower B, It should have
> been deleted as it was again created with another session{color}
> # {color:green}/e1 is deleted from Leader A and other Follower C{color}
