-------------------------------
I will take a look at this issue.
> ZkClientPool NPE after closing a connection
> -------------------------------------------
>
> Key: HELIX-598
> URL: https://issues.apache.org/jira/browse/HELIX-598
> Project: Apache Helix
> Issue Type: Bug
> Reporter: Jemiah Westerman
> Assignee: Lei Xia
>
> If a client gets a connection from ZkClientPool and then closes the
> connection by calling zkClient.close(), any future calls to getZkClient will
> NPE. The pool attempts to check if the connection is valid by calling
> "zkClient.getConnection().getZookeeperState() == States.CONNECTED", but for a
> closed connection the getConnection() call returns null.
> Further, there is currently no way to ask the pool itself to close
> connections. There is a reset method, but reset simply discards the reference
> to the connection without closing it. ZkConnectionPool.reset() should close
> connections before dereferencing them.
