[jira] [Created] (HBASE-17764) Solve TestMultiSlaveReplication flakiness

Stephen Yuan Jiang created HBASE-17764:
------------------------------------------

             Summary: Solve TestMultiSlaveReplication flakiness 
                 Key: HBASE-17764
                 URL: https://issues.apache.org/jira/browse/HBASE-17764
             Project: HBase
          Issue Type: Bug
          Components: test
            Reporter: Stephen Yuan Jiang
            Assignee: Stephen Yuan Jiang
            Priority: Minor


When I doing testing for a feature I am working on, the TestMultiSlaveReplication test was flaky.  TestMultiSlaveReplication#testMultiSlaveReplication would always pass when running alone; however, it would fail occasionally when running with the suite (the other test TestMultiSlaveReplication#testZKLockCleaner always run first and I suspect that it withhold some zookeeper resource, which caused the problem).  

After I set start and shutdown zk cluster before and after each test, I no longer see the problem.
