Tsuyoshi Ozawa commented on HADOOP-11098:
-----------------------------------------
All tests are not related to the patch.
Following tests are fails without patch - created HDFS-9195 and HDFS-9196 for
addressing the problem:

TestDelegationTokenForProxyUser.testWebHdfsDoAs:163
expected:<...ocalhost:44528/user/[Proxy]User> but
was:<...ocalhost:44528/user/[Real]User>
TestWebHdfsContentLength.testPutOp:116 expected:<0> but was:<null>
TestWebHdfsContentLength.testPutOpWithRedirect:130 expected:<[chunked]> but
was:<[0]>

The failures of TestCrcCorruption and TestGangliaMetrics are occasional one -
ran all tests locally and confirmed that they passes.
Thanks for the review, committing this shortly.
