[jira] [Created] (HBASE-14422) Fix TestFastFailWithoutTestUtil

stack created HBASE-14422:
-----------------------------

             Summary: Fix TestFastFailWithoutTestUtil
                 Key: HBASE-14422
                 URL: https://issues.apache.org/jira/browse/HBASE-14422
             Project: HBase
          Issue Type: Task
          Components: test
            Reporter: stack
            Priority: Minor


TestFastFailWithoutTestUtil has a unit test that does testInterceptorIntercept50Times Usually it passes but on occasion, the latching between thread 1 and thread 2 goes awry and the test hangs and the test hangs out. Depends on the hardware but it seems to happen about one in four runs here on an internal rig.

HBASE-14421 changed the wait-on-latch to timeout and do a thread dump and just let the test keep going.

This issue is about digging in on figuring why the hang up on latches and then fixing it so the test doesn't have to have the latch timeout. Hopefully the threaddump helps.

This one could be hard to fix since it not easy to reproduce. Marking it beginner anyways.
