stack reopened HBASE-14979:
---------------------------

Let me revert this for a while. In 1.2 alone, I see failures of TestRSKilledWhenInitializing failures with higher incidence in the 1.8 builds:

https://builds.apache.org/view/H-L/view/HBase/job/HBase-1.2/454/jdk=latest1.8,label=Hadoop/testReport/junit/org.apache.hadoop.hbase.regionserver/TestRSKilledWhenInitializing/testRSTermnationAfterRegisteringToMasterBeforeCreatingEphemeralNod/history/

Started about 3 days ago. Stacktraces look like this:

org.junit.runners.model.TestTimedOutException: test timed out after 180000 milliseconds
	at java.lang.Object.wait(Native Method)
	at java.lang.Thread.join(Thread.java:1245)
	at java.lang.Thread.join(Thread.java:1319)
	at org.apache.zookeeper.server.SyncRequestProcessor.shutdown(SyncRequestProcessor.java:213)
	at org.apache.zookeeper.server.PrepRequestProcessor.shutdown(PrepRequestProcessor.java:770)
	at org.apache.zookeeper.server.ZooKeeperServer.shutdown(ZooKeeperServer.java:478)
	at org.apache.zookeeper.server.NIOServerCnxnFactory.shutdown(NIOServerCnxnFactory.java:266)
	at org.apache.hadoop.hbase.zookeeper.MiniZooKeeperCluster.shutdown(MiniZooKeeperCluster.java:298)
	at org.apache.hadoop.hbase.HBaseTestingUtility.shutdownMiniZKCluster(HBaseTestingUtility.java:782)
	at org.apache.hadoop.hbase.HBaseTestingUtility.shutdownMiniCluster(HBaseTestingUtility.java:1090)
	at org.apache.hadoop.hbase.regionserver.TestRSKilledWhenInitializing.testRSTermnationAfterRegisteringToMasterBeforeCreatingEphemeralNod(TestRSKilledWhenInitializing.java:104)

Looks like hang in zk shutdown.

Zk-crew seem to be on about there being a hang in zk... see cited zk thread.
