Maximilian Michels created FLINK-3607:
-----------------------------------------
Summary: Decrease default forkCount for tests
Key: FLINK-3607
URL: https://issues.apache.org/jira/browse/FLINK-3607
Project: Flink
Issue Type: Improvement
Components: Build System
Reporter: Maximilian Michels
Assignee: Maximilian Michels
I'm seeing many tests failures because of timeouts:
https://builds.apache.org/job/flink-ci/1/testReport/
The {{forkCount}} is set to the aggressive value {{1.5C}}. We should consider
to reduce it at least to {{1C}} (1 fork per exposed physical/virtual core).
That could improve the test stability.
I did another test using {{1C}} on Jenkins and had only one failed test and a
decreased (!) run time: https://builds.apache.org/job/flink-ci/2/testReport/
1.5C: 1h 57m
1C: 1h 35m
I'll run some more tests to verify this.
