---------------------------------------
Summary: Lifecycle hooks support
Key: GRIFFIN-200
URL: https://issues.apache.org/jira/browse/GRIFFIN-200
Project: Griffin (Incubating)
Issue Type: New Feature
Reporter: Nikolay Sokolov
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 name (particular mechanism is yet to be
determined).
Proposed signature:
{code:none}
public interface JobLifecycleHook {
void beforeAddJob(AbstractJob js) throws Exception;
void afterAddJob(AbstractJob js) throws Exception;
void beforeOnAction(AbstractJob job, String action) throws Exception;
void afterOnAction(AbstractJob job, String action) throws Exception;
void beforeDeleteJob(AbstractJob job) throws SchedulerException;
void afterDeleteJob(AbstractJob job) throws SchedulerException;
}
{code}
