Subject [jira] [Created] (ACCUMULO-2434) Functional test MapReduce runner doesn't check return code of test
Date Wed, 05 Mar 2014 19:04:44 GMT
Sean Busbey created ACCUMULO-2434:
-------------------------------------

             Summary: Functional test MapReduce runner doesn't check return code of test
                 Key: ACCUMULO-2434
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2434
             Project: Accumulo
          Issue Type: Bug
          Components: test
    Affects Versions: 1.5.1, 1.4.5
            Reporter: Sean Busbey
            Priority: Critical
             Fix For: 1.4.6, 1.5.2


While testing ACCUMULO-2005, I had unusually fast MR test runs.

Drilling into individual task results showed the run was actually failing while reporting
the map task as successful.

the current test running class ignores the return code of the test process ([ref|https://github.com/apache/accumulo/blob/1.5.2-SNAPSHOT/test/src/main/java/org/apache/accumulo/test/functional/RunTests.java#L140])


Instead, we should check the status and fail the task if it returns an error.

Workaround: Job counters should show Success / Failure / Error count for tests. If none of
hte counters appear, consider all tests failed.
