> 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 GriffinHook {
> void onEvent(GriffinHookEvent event) throws Exception;
> }
> public interface GriffinHookEvent { ... }
> public interface JobEvent implements GriffinHookEvent { ... }
> public class BeforeJobCreated implements JobEvent { ... }
> public class AfterJobCreated implements JobEvent { ... }
> public class BeforeJobDeleted implements JobEvent { ... }
> public class AfterJobDeleted implements JobEvent { ... }
> public interface JobInstanceEvent implements GriffinHookEvent { ... }
> public class BeforeJobInstanceStart implements JobInstanceEvent { ... }
> public class AfterJobInstanceEnd implements JobInstanceEvent { ... }
> {code}
