[jira] Updated: (HADOOP-5349) When the size required for a path is -1, LocalDirAllocator.getLocalPathForWrite fails with a DiskCheckerException when the disk it selects is bad.

------------------------------

    Attachment: HADOOP-5349.txt

Seeing this issue many times on our clusters because of many tasks are getting failed.

Attaching patch that should fix this issue. The patch doesn't include any tests - as of now there are no tests verifying the algorithm of round-robin disk selection; writing these tests is a bit involving and can be done as part of another JIRA issue.
