Tian Hong Wang updated HDFS-4709:
---------------------------------
Attachment: HDFS-4709.patch
The main reason is that the whole unit test class uses only one single
Configuration object, so the configuration information in previous unit test
will affect the rear unit test.In testGetFileCheckSum() function, it seems to
be affected by
DFSConfigKeys.DFS_CLIENT_BLOCK_WRITE_LOCATEFOLLOWINGBLOCK_RETRIES_KEY. So it
should construct a clean Configuration object before each unit test begins.
> TestDFSClientRetries#testGetFileChecksum fails using IBM java 6
