--------------------------------------------

Hi Suresh

Sorry for the delay in responding. I think the test failures are unrelated
 1. testConcurrentJobs is failing because one file is not detected as corrupt 
and so block fixer does not fix it. This seems to be intermittent, since I 
tried running the test and it succeeded twice. I dont think this is related to 
federation. Perhaps we can track it separately?
 2. testFileBlockAndParityBlockMissingHar2 failed because of insufficient heap 
space when running a HAR job through LocalJobRunner. Again, unrelated to 
federation
 3. testJobQueues - Failed because of a timeout. Also, RAID changes cannot 
affect core mapred tests, so this must be unrelated.
