Vinod K V updated MAPREDUCE-890:
--------------------------------
Attachment: MAPREDUCE-890-20090904.txt
Attaching patch which should be applied over the latest patch at MAPREDUCE-856.
It follows a slight modification of the second proposal above, which is
bq. Set drwxrws--- on $job_cache and $dist_cache in all cases. This means
user's tasks CAN potentially create unwarranted files/dirs in the $job_cache or
$dist-cache or delete their own files themselves.
So now, the user-directory taskTracker/$user will have "2570 user-owner
task-tracker-group" and all the world under it will have "2570/0770 user-owner
task-tracker-group".
> After HADOOP-4491, the user who started mapred system is not able to run job.
