----------------------------------

             Summary: EventTimeWindowCheckpointingITCase.testPreAggregatedSlidingTimeWindow killed by maven watchdog on Travis
                 Key: FLINK-7346
                 URL: https://issues.apache.org/jira/browse/FLINK-7346
             Project: Flink
          Issue Type: Bug
          Components: DataStream API, Tests
    Affects Versions: 1.4.0
            Reporter: Nico Kruber
            Assignee: Nico Kruber


Several test runs fail with the watchdog killing the tests after receiving no output for 300s showing {{EventTimeWindowCheckpointingITCase.testPreAggregatedSlidingTimeWindow}} as one of the tests, sometimes with another test running in parallel. It does not seem to be hanging though and the only reason for this behaviour may be that the tests, especially with RocksDB, take very long with no output by each of the test methods in {{AbstractEventTimeWindowCheckpointingITCase}}. Thus adding output per method should fix the spurious test failures.

Some failing instances:
