Yi Liu commented on HADOOP-10886:
---------------------------------

Thanks Uma. The issue is caused by test case doesn't load the default configuration. [~clamb]
also found org.apache.hadoop.hdfs.TestDistributedFileSystem.testAllWithNoXmlDefaults  failed
and was caused by same issue, please fix them together.
