[jira] [Commented] (OOZIE-1536) Coordinator action reruns start a new workflow

["Shwetha G S (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OOZIE-1536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14154321#comment-14154321 ] 

Shwetha G S commented on OOZIE-1536:
------------------------------------

Here is what we can do. This should work for everybody:
1. Coord action re-run takes an addition optional flag -failed which re-runs only the failed nodes. This will re-run the existing workflow with RERUN_FAIL_NODES=true. But this will also honour coord concurrency.
2. Coord action re-run with no -failed option will use the existing feature of launching new workflow.
3. If a workflow has sub-workflow and some actions in the sub-workflow has failed, currently, workflow re-run with RERUN_FAIL_NODES=true will launch new sub-workflow. Instead, it should re-run only the failed nodes of the sub-workflow
4. Disable re-runs using the workflow directly if it has a parent. This applies to both cases where parent is coord action/another workflow. This check should be controlled using oozie-site config and should be disabled by default for backward compatibility

[~rohini], [~puru], [~sriksun], [~jaydeepmail], does this work for your usecases? Do you see any issues?

[~jaydeepmail], If everyone is ok with the approach, can you create sub-task for each of these and work on them separately? Thanks

> Coordinator action reruns start a new workflow and if existing workflow for the action is in running state, the same is not checked. Coord rerun can possibly do a workflow re-run to prevent this.
