Nikolay Sokolov updated GRIFFIN-200:
------------------------------------
Description:
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}
