Description

There appears to be an issue with the unit tests for the ZooKeeper State Provider. The client intermittently receives a ConnectionLossException when attempting to fetch the state from ZK. We need to properly address the unit test, but i propose that we should immediately mark the unit test as ignored until we have a chance to properly fix the test, as it is currently preventing master from building. We end up with the following stack trace:
