Subject [jira] [Commented] (HDFS-3890) filecontext mkdirs doesn't apply umask as expected
Date Wed, 05 Sep 2012 16:18:08 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13448853#comment-13448853
] 

Daryn Sharp commented on HDFS-3890:
-----------------------------------

Looks good me.  This mimics the behavior of other FC methods like create whereby it applies
the umask of the context, and then uses a primitive method to avoid {{DFSClient}} re-applying
the default umask.

> I was attempting to set the umask of my fileContext and then do a mkdirs, but the umask
wasn't applied as expected. 
> doneDirFc = FileContext.getFileContext(doneDirPrefixPath.toUri(), conf);
> doneDirFc.setUMask(JobHistoryUtils.HISTORY_DONE_DIR_UMASK);
> doneDirFc.mkdir(path, fsp, true);
> It appears to be using the default umask set in the conf (fs.permissions.umask-mode)
and overrode the umask I set in fileContext. I had the default umask set to 077 and set the
filecontext umask to 007.  The permissions on the directories it created were all rwx------.
