Raghu Angadi commented on HADOOP-2528:
--------------------------------------
This might be ok as temporary feature. IMHO such extra early checks are not
very useful and extra load on the server. I think its better to make sure in
rare cases where the permission is denied, the clear error info percolates up
to right places.
> check permissions for job inputs and outputs
