Jason Lowe commented on HADOOP-9287:
------------------------------------

Thanks for working on this, Andrey.  Overall patch looks good, and I agree the HDFS test changes
are tightly coupled with the changes in common.  It would be a pain to tackle these changes
in separate JIRAs, and since it's only modifying tests I'm inclined to keep that as one patch.
 However the changes to the hadoop-yarn tests have little to do with parallel testing in the
hadoop-common project and could trivially be separated.  Could you please move these to a
separate YARN JIRA?

[~cnauroth], have you had a chance to kick the tires on this patch for Windows?  Given that
the tests do not run in parallel by default, I don't believe the concern about race conditions
will affect the Windows build unless it explicitly asks for a parallel test run.  However
it would be good to get another datapoint to see if the tests run successfully in parallel
on Windows or if there's a test collision that only seems to happen on that platform.

> The maven surefire plugin supports parallel testing feature. By using it, the tests can
be run more faster.
