Subject [jira] [Commented] (HDFS-1869) mkdirs should use the supplied permission for all of the created directories
Date Thu, 19 May 2011 16:18:47 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1869?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13036274#comment-13036274
] 

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

Yes, mkdirs used to be posix compliant, but was subsequently broken.  This is directly related
to the linked HADOOP bug that mentioned the problem being introduced sometime after 0.20.9.
 The broken behavior was introduced when another feature was added (my memory is fuzzy, I
think it was quotas).

> 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.
