[jira] Commented: (HADOOP-5769) NameNode.mkdirs does not create directories owned by current group

["Tsz Wo (Nicholas), SZE (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-5769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12705661#action_12705661 ] 

Tsz Wo (Nicholas), SZE commented on HADOOP-5769:
------------------------------------------------

In [HDFS Permissions Guide |http://hadoop.apache.org/core/docs/r0.20.0/hdfs_permissions_guide.html#Overview], it says,
"... When a file or directory is created, its owner is the user identity of the client process, and its group is the group of the parent directory (the BSD rule)."

Thus, this is not a bug.

> The second argument to PermissionStatus should possibly be set by the first group listed in the current UGI.
