title: stormconf.ser doesn't exist error on worker
body: <p>I have a Storm cluster with 2 nodes and 1 ZooKeeper. One of the worker dies because of the following error. Does any one have an idea on why <em>stormconf.ser</em> file is getting deleted?</p>
  
  <p>I am using 0.9.2 Storm and 3.4.6 ZK version.</p>
