> Recursive mkdir removes sticky bit when adding implicit u+wx to intermediate

> Project: Hadoop HDFS

>
> When performing a recursive {{mkdirs}} operation, the NameNode takes the
> provided {{FsPermission}} and applies it to the final directory that is
> created. The NameNode also uses these permissions when creating intermediate
> directories, except it promotes with {{u+wx}} (i.e. {{mode |= 0300}}) in
> order to ensure that there are sufficient permissions on the new directory to
> create further subdirectories within it.
> Currently the code that does this permission promotion uses the
> three-argument {{FsPermission}} constructor, which sets the sticky bit to
> {{false}}. I think this is probably not the intended behaviour, so I'm
> opening a bug. I'll attach a patch shortly that changes the behaviour so that
> the sticky bit is always retained.
