Michi Mutsuzaki updated ZOOKEEPER-1870:
---------------------------------------
Description:
I'm seeing lots of the following failure. Seems like a flakey test (passes
every so often).
{noformat}
junit.framework.AssertionFailedError: client could not connect to reestablished
quorum: giving up after 30+ seconds.
at
org.apache.zookeeper.test.ReconfigTest.testNormalOperation(ReconfigTest.java:143)
at
org.apache.zookeeper.server.quorum.StandaloneDisabledTest.startSingleServerTest(StandaloneDisabledTest.java:75)
at
org.apache.zookeeper.JUnit4ZKTestRunner$LoggedInvokeMethod.evaluate(JUnit4ZKTestRunner.java:52)
{noformat}
I've found 3 problems:
1. QuorumCnxManager.Listener.run() leaks the socket depending on when the
shutdown flag gets set.
2. QuorumCnxManager.halt() doesn't wait for the listener to terminate.
3. QuorumPeer.shuttingDownLE flag doesn't get reset when restarting the leader
election.

I've found 3 problems that
1. Prevent socket leak in QuorumCnxManager.Listener.run().
2. Make QuorumCnxManager.halt() join the listener.
3. Reset QuorumPeer.shuttingDownLE flag when restarting the leader election.
