public void testMasterZKSessionRecoveryFailure()
                                        throws Exception

Master recovery when the znode already exists. Internally, this test differs from testMasterSessionExpired() because here the master znode will exist in ZK.

Throws:

Exception

testRegionAssignmentAfterMasterRecoveryDueToZKExpiry

public void testRegionAssignmentAfterMasterRecoveryDueToZKExpiry()
                                                          throws Exception

Tests that the master does not call retainAssignment after recovery from expired zookeeper session. Without the HBASE-6046 fix master always tries to assign all the user regions by calling retainAssignment.

Throws:

Exception

testLogSplittingAfterMasterRecoveryDueToZKExpiry

public void testLogSplittingAfterMasterRecoveryDueToZKExpiry()
                                                      throws Exception

Tests whether the logs are split when master recovers from a expired zookeeper session and an RS goes down.
