[jira] [Created] (FLINK-6287) Flakey JobManagerRegistrationTest
Nico Kruber created FLINK-6287:
----------------------------------
Summary: Flakey JobManagerRegistrationTest
Key: FLINK-6287
URL: https://issues.apache.org/jira/browse/FLINK-6287
Project: Flink
Issue Type: Bug
Components: JobManager
Affects Versions: 1.3.0
Environment: unit tests
Reporter: Nico Kruber
There seems to be a race condition in the "{{JobManagerRegistrationTest.The JobManager should handle repeated registration calls}}" (scala) unit test.
Every so often, especially when my system is under load, this test fails with a timeout after seeing the following messages in the log4j INFO outputs:

Note that there is also an exception for the {{MetricQueryService}} in the log which does not really affect the unit test though except for metrics not being reported.
