[jira] [Commented] (OOZIE-3267) Re-run coord action without checking input dependencies

    [ https://issues.apache.org/jira/browse/OOZIE-3267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16493489#comment-16493489 ] 

Peter Cseh commented on OOZIE-3267:
-----------------------------------

You can already achieve this using [conditional input logic in coordinators|https://oozie.apache.org/docs/5.0.0/CoordinatorFunctionalSpec.html#a6.10._Conditional_coordinator_input_logic], can't you?

> A coord action will get stuck in WAITING status if some of its input dependencies are missing.
> However, there are cases where users want to force start the coord action without checking input dependencies.
> For example, the process of training a day model need 24 different hour input files to get best accuracy ( 23 input files are also OK, but the accuracy may decrease).
> In some cases (e.g., one hour input file get delayed), it is more important to get the model on time than high accuracy.
