Konstantin Shvachko commented on MAPREDUCE-2767:
------------------------------------------------
Aren't we trying to remove the entire palm because one nail grew ugly?
We can just turn it off by throwing, e.g. UnsupportedOperationException on an
attempt to use it. And then turn it back on when the fix is provided.

> There's a potential security hole in the task-controller as it stands. Based
> on the discussion on general@, removing task-controller from the 0.22 branch
> will pave way for 0.22.0 release. (This was done for the 0.21.0 release as
> well: see MAPREDUCE-2014.) We can roll a 0.22.1 release with the
> task-controller when it is fixed.
