[jira] [Resolved] (MAPREDUCE-2390) JobTracker and TaskTrackers fail
with a misleading error if one of the mapreduce.cluster.dir has unusable
permissions / is unavailable.

Resolution: Duplicate
Fix Version/s: 0.22.0
Release Note: (was: Ignore bad locations in mapreduce.cluster.dir / mapred.local.dir directories in a proper fashion.)
Resolving as Duplicate of MAPREDUCE-1382 (Which is fixed in 0.22)

> Key: MAPREDUCE-2390
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2390
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobtracker, tasktracker
> Affects Versions: 0.20.2
> Environment: CDH3 and Apache 0.20 || Linux
> Reporter: Harsh J
> Assignee: Harsh J
> Labels: configuration, directory-permissions, mapreduce
> Fix For: 0.22.0
>

> To reproduce, have a mapred.local.dir property set to a few directories. Before starting up the JT, set one of these directories' permission as 'd---------', and then start the JT/TT. The JT, although it tries to ignore this directory, fails with an odd and misleading message claiming that its configured address in use.
> Fixing the permission clears this issue!
> This was also reported in the mailing lists by Ted Yu, quite a few months ago. But I had forgotten about filing a bug for it here. Still seems to happen. A log is attached below.
