Subject [jira] [Commented] (HADOOP-14277) TestTrash.testTrashRestarts is flaky
Date Wed, 05 Apr 2017 15:20:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14277?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15957016#comment-15957016

Weiwei Yang commented on HADOOP-14277:

Hi [~ebadger]

The purpose of this test was not to test a trash policy implementation, i.e {{TrashPolicyDefault}}.
It was to use some fake implementations to test trash API. Because the trash policy is plug-able,
we need to ensure the public API is stable. Does that make sense?

Maybe we should increase the trash interval from 50ms to 500ms, 50ms seems to be too aggressive?
 And were you seeing this failure in jenkins job results or while you are doing some other
stuff related to trash? Please let me know.
