Vinod K V commented on HADOOP-4491:
-----------------------------------
Going forward with the latest proposal.
Salient points:
- Same directory structure as what is in the trunk.
- Actions taken up the linux-taskcontroller:
-- initializeJob
--- sudo chown user:mapred -R taskTracker/jobcache/$jobid
--- sudo chmod 570 -R taskTracker/jobcache/$jobid
-- initializeTask
--- sudo chown user:mapred -R taskTracker/jobcache/$jobid/$attemptid/
--- sudo chmod 770 -R taskTracker/jobcache/$jobid/$attemptid/
--- sudo chmod +s taskTracker/jobcache/$jobid/$attemptid
---
--- sudo chown user:mapred log-dir/userlogs/$attemptid
--- sudo chmod 770 log-dir/userlogs/$attemptid
--- sudo chmod +s log-dir/userlogs/$attemptid
child umask 0007
> Per-job local data on the TaskTracker node should have right access-control
