Subject [jira] [Created] (MAPREDUCE-5446) TestJobHistoryEvents and TestJobHistoryParsing have race conditions
Date Fri, 02 Aug 2013 18:11:48 GMT
Jason Lowe created MAPREDUCE-5446:
-------------------------------------

             Summary: TestJobHistoryEvents and TestJobHistoryParsing have race conditions
                 Key: MAPREDUCE-5446
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5446
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2, test
    Affects Versions: 2.1.0-beta
            Reporter: Jason Lowe


TestJobHistoryEvents and TestJobHistoryParsing are not properly waiting for MRApp to finish.
 Currently they are polling the service state looking for Service.STATE.STOPPED, but the service
can appear to be in that state *before* it is fully stopped.  This causes tests to finish
with MRApp threads still in-flight, and those threads can conflict with subsequent tests when
they collide in the filesystem.
