Subject [jira] [Commented] (HDFS-4586) TestDataDirs.testGetDataDirsFromURIs fails with all directories in dfs.datanode.data.dir are invalid
Date Mon, 11 Mar 2013 22:29:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4586?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13599404#comment-13599404
] 

Chris Nauroth commented on HDFS-4586:
-------------------------------------

I really appreciate you picking up this fix so quickly.  :-)

{code}
    public DataNodeDiskChecker(FsPermission expectedPermission) {
    }
{code}

It looks like the constructor forgot to initialize expectedPermission.  I added {{this.expectedPermission
= expectedPermission;}} before I tested the patch.  I verified that it was successful on both
Mac and Windows.

If you can upload a new patch with that small change, then I am +1.  I agree with the approach.

Thanks again!
