Subject [jira] [Commented] (HDFS-1869) mkdirs should use the supplied permission for all of the created directories
Date Thu, 12 May 2011 19:51:47 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1869?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13032619#comment-13032619
] 

Daryn Sharp commented on HDFS-1869:
-----------------------------------

Yes, it should.  I worried about the same thing, but I believe I found existing code that
implicitly assumed 0300 on dir creates and/or the namenode didn't bother checking permissions
as it created the intermediate directories.  My memory is a bit foggy, I'll double check.

> Mkdirs only uses the supplied FsPermission for the last directory of the path.  Paths
0..N-1 will all inherit the parent dir's permissions -even if- inheritPermission is false.
 This is a regression from somewhere around 0.20.9 and does not follow posix semantics.
