Subject [jira] [Commented] (HDFS-2505) Add a test to verify getFileChecksum works with ViewFS
Date Thu, 02 Feb 2012 07:49:54 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13198585#comment-13198585
] 

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)
