title: Zookeeper error connection loss exception
body: <p>I'm running a SeqWare VM on an amazon EC2 instance I'm trying to use the SeqWare query engine to query data from VCF files. When I first launch the instance and follow the instructions to import data, It works fine, and continues to work until I stop the instance. When I restart it. It won't let me import anything, nor create a new workspace. It always returns the error below. I looked at the processes and found that none of the required nodes were running, so I logged into root and went to the <code>etc/init.d</code> directory and start everything again, at which point, when T try to import data, I don't even get an error and I have to stop the process.</p>
