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 should use the supplied permission for all of the created directories

> 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.
