Ravi Prakash commented on HDFS-2505:
------------------------------------

Thanks Jitendra! Unit tests were added as part of HADOOP-7770 for the changes 
made in ViewFS.java and ViewFileSystem.java. There weren't any changes in HDFS 
code. Could you please specify what method / interface you'd like tested?
Would this test not make sense, because it might break without any changes in 
HDFS code (if there are changes in the Hadoop getFileChecksum code)? If so, we 
can close this JIRA as invalid. Or do we WANT that check? So that if Hadoop 
Common changes things, HDFS tests break and we are notified to fix the issue in 
HDFS also?

> 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)
