hi Nikolay Sokolov,
I suggest you make your proposal and discuss in our dev mailing list for the
design.
Let the community discuss and decide.
When design is fully discussed and debated, we can do a quick implementation
for this hook.
What do you think?
Thanks,
William

> Key: GRIFFIN-200
> URL: https://issues.apache.org/jira/browse/GRIFFIN-200
> Project: Griffin (Incubating)
> Issue Type: New Feature
> Reporter: Nikolay Sokolov
> Assignee: William Guo
> Priority: Minor
>
> In some environments, users might want to perform certain actions
> before/after job is created, before/after job is activated, before/after job
> is deleted, and so on.
> To fullfill that need, some hook plugin mechanism can be provided, similar to
> what Hive is doing. User would place respective jar files into Service module
> classpath at deployment time, and would specify class names using some
> annotation or using property listing class names (particular mechanism is yet
> to be determined).
> Proposed signature:
> {code:none}
> public interface JobLifecycleHook {
> void onJobEvent(JobLifecycleEvent event) throws Exception;
> }
> public class BeforeJobCreated implements JobLifecycleEvent { ... }
> public class AfterJobCreated implements JobLifecycleEvent { ... }
> public class BeforeJobDeleted implements JobLifecycleEvent { ... }
> public class AfterJobDeleted implements JobLifecycleEvent { ... }
> {code}
