[jira] [Created] (YARN-11642) Fix Flask Test TestTimelineAuthFilterForV2#testPutTimelineEntities

Shilun Fan created YARN-11642:
---------------------------------

             Summary: Fix Flask Test TestTimelineAuthFilterForV2#testPutTimelineEntities
                 Key: YARN-11642
                 URL: https://issues.apache.org/jira/browse/YARN-11642
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: timelineservice
    Affects Versions: 3.5.0
            Reporter: Shilun Fan
            Assignee: Shilun Fan


Our current unit tests are all executed in parallel. 
TestTimelineAuthFilterForV2#testPutTimelineEntities will report an error during execution:

{code:java}
[main] collector.PerNodeTimelineCollectorsAuxService (StringUtils.java:startupShutdownMessage(755)) - failed to register any UNIX signal loggers: 
java.lang.IllegalStateException: Can't re-install the signal handlers.
{code}

We can solve this problem by changing static initialization to new Object.
