RaidNode should write temp files on /tmp and add random numbers to their names to avoid conflicts
-------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-1659
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1659
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: contrib/raid
    Affects Versions: 0.22.0
            Reporter: Rodrigo Schmidt
            Assignee: Rodrigo Schmidt
             Fix For: 0.22.0


The RaidNode methods to raid files and recover them should write recovery and tmp files on /tmp instead of /raid.

Besides that, filenames should have a random number appended to them to avoid conflicts. This makes the code safer and avoids errors when multiple recoveries run in parallel.
