Harsh J commented on MAPREDUCE-2390:
------------------------------------
MAPREDUCE-1382 fixes this, but what's odd is that:
JT says this:
{code}
2011-06-12 00:00:34,924 WARN org.apache.hadoop.util.MRAsyncDiskService: Cannot
create toBeDeleted in
/Users/harshchouraria/Work/installs/temp-space/mapred/local1. Ignored.
{code}
TT does this instead:
{code}
2011-06-12 00:00:35,980 WARN org.apache.hadoop.util.DiskChecker: Incorrect
permissions were set on
/Users/harshchouraria/Work/installs/temp-space/mapred/local1, expected:
rwxr-xr-x, while actual: ---------. Fixing...
{code}
May be worth making JT do this too, if its gonna use {{mapred.local.dir}} (or
w/e its new alias is) after all.
> JobTracker and TaskTrackers fail with a misleading error if one of the
> mapreduce.cluster.dir has unusable permissions / is unavailable.

> 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
>
> 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.
