      Description

      Some of the tests are consistently failing for me and intermittently on hudson.

      Posting discussion from mailing list below.

      Vishal,
      Can you please open a jira for this and mark it as a blocker for 3.4
      release? Looks like its transient:

      https://builds.apache.org/job/ZooKeeper-trunk/

      The latest build is passing.

      thanks
      mahadev
