Gabor Gevay created FLINK-2378:
----------------------------------
Summary: complexIntegrationTest1 and testGroupByFeedback sometimes
fail on Windows
Key: FLINK-2378
URL: https://issues.apache.org/jira/browse/FLINK-2378
Project: Flink
Issue Type: Bug
Components: Streaming
Reporter: Gabor Gevay
Priority: Minor
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.
