Description

Makes the code run slightly faster and avoids possible problems in matching the right filesystem like the stale cache reported in HADOOP-6097.

This is a minor improvement for trunk, but it is really helpful for people running RAID on earlier releases susceptible to HADOOP-6097, since RAID would crash on them.

Issue Links

• depends upon: MAPREDUCE-1510 RAID should regenerate parity files if they get deleted
• is depended upon by: MAPREDUCE-1518 On contrib/raid, the RaidNode currently runs the deletion check for parity files on directories too. It would be better if it didn't.
