[jira] [Created] (FLINK-3607) Decrease default forkCount for tests

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.
