Hairong Kuang updated HADOOP-1873:
----------------------------------
Attachment: mapred2.patch
After some thought, I revert JobTracker's old behavior, i.e., removing the
mapreduce system directory at the start up time. It's recommended that the
jobtracker is run as the same user as the namenode. If not, mapred system
directory should be under a directory which is writable by the user who starts
the namenode. I will incorporates Nicholas's comment after HADOOP-1298 is
committed.
> User permissions for Map/Reduce

> HADOOP-1298 and HADOOP-1701 add permissions and pluggable security for DFS
> files and DFS accesses. Same users permission should work for Map/Reduce jobs
> as well.
> User persmission should propegate from client to map/reduce tasks and all the
> file operations should be subject to user permissions. This is transparent to
> the user (i.e. no changes to user code should be required).
