Date Fri, 09 Oct 2015 11:33:26 GMT
Gabor Gevay created FLINK-2839:

             Summary: Failing test: OperatorStatsAccumulatorTest.testAccumulatorAllStatistics
                 Key: FLINK-2839
                 URL: https://issues.apache.org/jira/browse/FLINK-2839
             Project: Flink
          Issue Type: Bug
          Components: flink-contrib
            Reporter: Gabor Gevay
            Priority: Minor

I saw this test failure:

Tests run: 4, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 7.633 sec <<< FAILURE!
- in org.apache.flink.contrib.operatorstatistics.OperatorStatsAccumulatorTest
 Time elapsed: 1.5 sec  <<< FAILURE!
java.lang.AssertionError: The total number of heavy hitters should be between 0 and 5.
	at org.junit.Assert.fail(Assert.java:88)
	at org.junit.Assert.assertTrue(Assert.java:41)
	at org.apache.flink.contrib.operatorstatistics.OperatorStatsAccumulatorTest.testAccumulatorAllStatistics(OperatorStatsAccumulatorTest.java:151)

Full log [here|https://s3.amazonaws.com/archive.travis-ci.org/jobs/84469788/log.txt].

Maybe the test should set a constant seed to the {{Random}} object.
