Mohammad,
As I've mentioned in the parent JIRA (OOZIE-592):
------------------------------------------------------------------------
Current WF library implementation (lite) has the following issues/limitations:
* Under certain conditions kill/failure all running actions are not being
properly killed (leaving things in odd states and/or runaway actions)
* Exceptions are properly propagated handled
* start/end/kill/fork/join nodes do not provide hooks to create entries in the
DB in the WF actions table (useful for WF visualization)
In addition, the following new features would allow more flexible WF
programming:
* support for a SUSPEND node, to programmatically suspend a WF in certain
condition.
* support for SHARD/UNSHARD nodes, similar to FORK/JOIN but it is a single
execution lane that gets multiplexed N times
------------------------------------------------------------------------
Furthermore, initially I've tried to work on the existing WF lite, but I've
found quite difficult to add some of this new functionality in the existing
signal logic. Because of that I've started from scratch copying over much of
the code from WF lite.
