Sticky bit for directories
--------------------------
Key: HADOOP-3953
URL: https://issues.apache.org/jira/browse/HADOOP-3953
Project: Hadoop Core
Issue Type: Improvement
Components: dfs
Reporter: Koji Noguchi
Our users (especially Pig) heavily use /tmp for temporary storage.
Permission are set to 777.
However, this means any users can rename and also remove (by moving to .Trash)
other users directories and files.
It would be nice if we can have a sticky bit like unix.
Copy&Pasted from manpage.
STICKY DIRECTORIES
When the sticky bit is set on a directory, files in that directory
may be unlinked or renamed only by
root or their owner. Without the sticky bit, anyone able to write to
the directory can delete or rename
files. The sticky bit is commonly found on directories, such as /tmp,
that are world-writable.
