> This only happens when Maven runs the test, I can't trigger it from the IDE.
> At first I thought that something is wrong with having shared variables between the tests in ComplexIntegrationTest, but when I eliminated the shared variables, the test still fails.
> The error msgs:
> testGroupByFeedback(org.apache.flink.streaming.api.IterateTest)
> Time elapsed: 12.091 sec  <<< ERROR!
> org.apache.flink.runtime.client.JobExecutionException: Job execution failed.
