YARN-2566. Local dir creation

[Karthik Kambatla <ka...@cloudera.com>]

Hi folks,

I just wanted to bring YARN-2566 to your notice - the JIRA proposes to pick
directory with most available space instead of the first directory.

While I believe it is definitely an improvement over picking the first
directory always, I understand this can cause hot-spotting on nodes with
widely varied availabilities.

If you have opinions on picking a local directory, please comment on the
JIRA.

Thanks
Karthik
