Mikhail Antonov commented on HBASE-11517:
-----------------------------------------
So..if i comment out the last line in testReplicaAndReplication() test, which
is HTU2.shutdownMiniCluster();, test works fine. Seems like something's wrong
with the way we share hconnections in local hbase cluster - when we shutdown
minicluster2, short circuit connection in master running in minicluster1 is
also closed.
Also everything works and test passes if I do start/stop minicluster1 before
and after each test. Something wrong with connection sharing.
