             Summary: Eliminate Thread.sleep() calls in TestMemoryLocks
                 Key: OOZIE-2584
                 URL: https://issues.apache.org/jira/browse/OOZIE-2584
             Project: Oozie
          Issue Type: Bug
            Reporter: Peter Bacsko
            Assignee: Peter Bacsko
            Priority: Minor


There are a lot of Thread.sleep() calls in TestMemoryLocks.

For example:
{code}
        new Thread(l1).start();
        Thread.sleep(500);
        new Thread(l2).start();
        Thread.sleep(500);
{code}

This solution is very fragile. On a slower build machine, Thread2 might 
actually start earlier than Thread1, causing test failure.

Eliminate sleeps and use a more stable approach for start/stop coordination 
(possibly CountDownLatches).
