zookeeper unexpected exception causing shutdown while sock still open
<p>I am getting quite a few major issues in Cloudera Hadoop 2.0 cluster that coincides with the following errors on zookeeper that happens many times a day.</p>

<p>I am unable to find the root cause of this.</p>

<p>Any help is appreciated.</p>
