Vinod K V updated HADOOP-4491:
------------------------------
Attachment: HADOOP-4491-20090707.txt
HADOOP-4491-20090707-common.txt
Adding new patches:
- Cleaned up the common part of the code a little. After going through the
patch, realized that the changes to LocalDirAllocator can be done away with and
so reverted most of the changes. Now we only need a way to set permissions and
so retained setPermissions and related api but moved them to FileUtil.
- Found a bug related to task localization. With the attached patch, we create
attempt directories also on all the disks. This has to be done because job
directory is writable only by the TT and so the child cannot create
non-existing attempt dirs on certain disks on demand.
Freezing up any further changes till review comments are put up.
> Per-job local data on the TaskTracker node should have right access-control
