Milind Bhandarkar commented on MAPREDUCE-2767:
----------------------------------------------
For some time after the merge of three projects (common, hdfs, mapreduce), the
test-patch ant target was broken (since it tried to apply the patch from inside
the mapreduce directory (where build.xml exists), whereas the patch is
generated from the top level. This never got fixed in the 0.22 branch, and so
my "ant test-patch" is failing in the patch application step.
After manually applying the patch, I ran ant test in mapreduce directory, and I
get only unrelated failures.

> 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.
