Review request for Falcon.


Changes
-------

Updating the patch based on review comments


Repository: falcon-git


Description
-------

In distributed mode, when parallel update command are issued for same entity, they are not
syncronized.
This leads to multiple coordinators being spawned in Oozie.

We need to ensure that the update method is syncronized.
