Subject [jira] [Resolved] (HDFS-1322) DistributedFileSystem.mkdirs(dir, dirPermission) doesn't set the permissions of created dir to dirPermission
Date Tue, 25 Sep 2012 22:04:09 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1322?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Colin Patrick McCabe resolved HDFS-1322.
----------------------------------------

    Resolution: Invalid

As Suresh commented, this is working as designed.

If you don't want your permissions to be altered by the umask, you can set your client's umask
to 0 using this code:
{code}
conf.set(CommonConfigurationKeys.FS_PERMISSIONS_UMASK_KEY, "0");
[... create FS using conf ...]
{code}

Try {{man umask}} for more information about umask.

> DistributedFileSystem.mkdirs(dir, dirPermission) calls DFSClient.mkdirs(dir, dirPermission)
to create directory and then set permissions to (dirPermission & ~umask). Is this the
intended behaviour ? I expect it to set permissions of dir to dirPermission instead of doing
an AND with ~umask ---- similar to what 'chmod -m mode' does.
> The javadoc of DFSClient.mkdirs() says that the permissions of created dir will be set
to dirPermission, which is not done currently. This needs to be modified based on the actual
behaviour.
> This is not an issue in RawLocalFileSystem.
