------------------------------
I got the following test failures running test suite:
{code}
[junit] Test org.apache.hadoop.fs.TestFsShellReturnCode FAILED
[junit] Test
org.apache.hadoop.hdfs.server.namenode.TestNNThroughputBenchmark FAILED
[junit] Test

[junit] Test org.apache.hadoop.tools.rumen.TestRumenJobTraces FAILED
[junit] Test org.apache.hadoop.mapred.TestFairSchedulerPoolNames FAILED
{code}
In TEST-org.apache.hadoop.hdfs.server.namenode.TestNNThroughputBenchmark.txt, I
found:
{code}

I am not sure if the test failures were related to my patch.
