Sangjin Lee updated YARN-5354:
------------------------------
    Attachment: YARN-5354.01.patch

Posted patch v.1.

Switched to using a test-specific storage directory. I realize that the 
{{FileSystemTimelineWriterImpl}} default value should be handled separately. 
I'll file a separate JIRA.

> TestDistributedShell.checkTimelineV2() may fail for concurrent tests

> {{TestDistributedShell.checkTimelineV2()}} uses the default (hard-coded) 
> storage root directory. This is brittle against concurrent tests. We should 
> use a unique storage directory for the unit tests.
