             Summary: Race in CompactionExecutorTest
                 Key: CASSANDRA-17239
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17239
             Project: Cassandra
          Issue Type: Bug
          Components: Test/unit
            Reporter: Jon Meredith
            Assignee: Jon Meredith


CompactionExecutorTest has a race between the runnable/callable under test completing
and the {{afterExecute}} method stashing it for the test.  Replace the wait/sleep loop
with a {{SimpleCondition}} that is signaled once the test task throwable has been recorded.

This seems fairly hard to hit but has happened on CI.  It took about 2600 iterations on my MacBook to trigger, but you can artificially hit frequently by adding a sleep at the start of the afterExecute method.
