What could cause persistent client disconnects while trying to run Hadoop Zookeeper through a cloud provider?

We are trying to set up Zookeeper in a virtual environment through our cloud provider. On a regular basis we are getting client disconnects. Is there a common cause for these disconnects to keep happening?

You didn't mention your timeout config, but it should be set pretty high for your situation.  There can be a lot of latency issues that potentially cause problems in a virtual environment.  Try configuring timeout at something high like 10 seconds and see if you notice an improvement.

You might want to check the documentation or discuss Hadoop on their mailing list. There are probably some other folks who have seen similar issues.
