Subject [jira] [Created] (IMPALA-5198) test_exchange_delays custom cluster test failed on s3 tests
Date Tue, 11 Apr 2017 18:28:41 GMT
Matthew Jacobs created IMPALA-5198:
--------------------------------------

             Summary: test_exchange_delays custom cluster test failed on s3 tests
                 Key: IMPALA-5198
                 URL: https://issues.apache.org/jira/browse/IMPALA-5198
             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
    Affects Versions: Impala 2.8.0
            Reporter: Matthew Jacobs
            Priority: Blocker


On the nightly core s3 tests, the custom cluster test test_exchange_delays failed. It looks
like the query failed for an unexplained reason. It says 'aborted' but we need to look at
it more closely.
