Chris Nauroth commented on HADOOP-9555:
---------------------------------------

The scope of this issue is to upgrade Hadoop Common's ZooKeeper version after resolution of that bug and get the failing tests to run and pass consistently on Windows.  This bug causes sporadic failures in the following tests on Windows: {{TestActiveStandbyElectorRealZK}}, {{TestFailoverController}}, {{TestZKFailoverController}}, {{TestZKFailoverControllerStress}}.

> ZOOKEEPER-1702 tracks a client connection management bug.  The bug can cause an unexpected TCP RST that ultimately prevents delivery of a session expiration event.  The symptoms of the bug seem to show up more frequently on Windows than on other platforms (though it's not really a Windows-specific bug).
