Arun C Murthy commented on HADOOP-2528:
---------------------------------------
I'm with Doug on the need for failing early if either of the input or output
directories aren't readable/writable.
I'm wondering if it makes sense to add utility apis in fs which given a
directory name checks for existence, validates against given set of permissions
etc. We could then use this to validate the job inputs via a single rpc, rather
than one per file as today (without this patch). Thoughts?
