Jitendra Nath Pandey commented on HDFS-2505:
--------------------------------------------

 ViewFS also has getFileChecksum method similar to ViewFileSystem. Since this 
patch adds a test for ViewFileSystem, probably a similar test in ViewFS also 
makes sense. By Hdfs, I actually meant Hdfs.java which is an AbstractFileSystem 
implementation unlike DistributedFileSystem (which is FileSystem). If you use 
ViewFS for hdfs, it will use Hdfs underneath, therefore you shouldn't have to 
do anything explicit for Hdfs.

> Please refer to HADOOP-7770. getFileChecksum was failing on files such as 
> /tmp/someFile, but working fine for /someDir/someFile.
> The fix is in HADOOP-7770 but we should have a test in HDFS which checks this 
> functionality (this test will fail until HADOOP-7770 is checked in)
