Subject [jira] [Updated] (HDFS-1322) DistributedFileSystem.mkdirs(dir, dirPermission) doesn't set the permissions of created dir to dirPermission
Date Wed, 27 Jul 2011 19:20:09 GMT

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

Plamen Jeliazkov updated HDFS-1322:
-----------------------------------

    Attachment: HDFS-1322.patch

This patch should fix that. But this is not clear whether this is a bug or not. It could be
that the JavaDocs are out of date and that umask'ing the permissions was a valid operation.

Anyway, here is the patch to set DFSClient's .mkdirs() method use the parameter permissions
and NOT umasking them.

> 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.
