["Jaydeep Vishwakarma (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OOZIE-2129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14342919#comment-14342919 ] 

Jaydeep Vishwakarma commented on OOZIE-2129:
--------------------------------------------

1. Added back the launch time in filter.
3. Yes this patch will fix the issue. I meant without this patch it will not work.
For 2 and 5 :  "they have to implement some code"  propagation.xml is the way for the launcher to share details in case they need to take advantage of it, since there are no other simple ways or established contract to share info in a backward compatible way.  
6. Yes, when any coord_action/workflow/launcher are running, oozie will not allow to rerun. The issues comes when the job launched by launcher is in running state and coord_action/workflow/launcher is in killed state, In this case, before rerunning the coord_action/workflow/launcher none of the previous launched job is running on cluster. Check my second comment in the same jira that explain in what cases this condition can occur.

> OOZIE-1722 ensures that child job is killed at launcher restart. But this doesn't work for java actions as the tag is not passed to the child job.
> In case of coord action rerun, new workflow is created and hence new tag. So, it doesn't ensure old child job is killed at launcher start
