Mohammad Kamrul Islam commented on OOZIE-592:
---------------------------------------------
I like this JSON object concept. Do we think we need to keep the current
versioning concept to avoid both forward and backward compatibility?
> new WF library implementation (lite2)

> Key: OOZIE-592
> URL: https://issues.apache.org/jira/browse/OOZIE-592
> Project: Oozie
> Issue Type: Improvement
> Reporter: Alejandro Abdelnur
> Assignee: Alejandro Abdelnur
>
> 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
> These 2 new features would be exposed in a new schema.
> The implementation approach for this would be broken down into a few JIRAs:
> * WF lite2 implementation with testcases
> * WF lite2 node handlers
> * WF lite2 service
