Ramkumar Vadali commented on MAPREDUCE-2368:
--------------------------------------------

The failed contrib tests were in mumak and raid. I will take a look at the raid test failure.
     [exec]     [junit] Test org.apache.hadoop.mapred.TestSimulatorEndToEnd FAILED (timeout)
     [exec]     [junit] Test org.apache.hadoop.mapred.TestSimulatorSerialJobSubmission FAILED
(timeout)
     [exec]     [junit] Test org.apache.hadoop.mapred.TestSimulatorStressJobSubmission FAILED
(timeout)
     [exec]     [junit] Test org.apache.hadoop.raid.TestBlockFixer FAILED (timeout)

> The patch for MAPREDUCE-2248 did not handle zero-length files correctly, which leads
to ArrayIndexOutOfBoundsException when opening a zero-length file. That case needs special
handling.
