Connection to ZooKeeper hangs forever using Java client

[arman-yekkehkhani]

I am trying to obtain a connection from zookeeper instances using Java client version 1.2.0. Unfortunately, the connection to zookeeper itself can not be established and remains in waiting status. Upon further investigation, I found out the root cause is the transitive dependency to zkClient library.

<dependency>
      <groupId>com.101tec</groupId>
      <artifactId>zkclient</artifactId>
      <version>0.11</version>
</dependency>

I also tried older versions of Java client, version 0.9.3, this issue does not appear in this version as it is relying on an older version of zkClient.

One possible workaround is to use the zkClient provided by apache-helix zkClient.
