[jira] [Commented] (FLINK-3607) Decrease default forkCount for
tests
[ https://issues.apache.org/jira/browse/FLINK-3607?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15191019#comment-15191019 ]
Robert Metzger commented on FLINK-3607:
---------------------------------------
I think you can pass a custom fork count using maven properties if a build environment is not capable of handling the parallelism.
> 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
> Labels: test-stability
>
> 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.
