Subject [jira] [Created] (YARN-5759) Capability to register for a notification/callback on the expiry of timeouts for an application

Gour Saha created YARN-5759:
-------------------------------

             Summary: Capability to register for a notification/callback on the expiry of
timeouts for an application
                 Key: YARN-5759
                 URL: https://issues.apache.org/jira/browse/YARN-5759
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: resourcemanager
            Reporter: Gour Saha


There is a need for the YARN native services REST-API service, to take certain actions once
a timeout of an application expires. For example, an immediate requirement is to destroy a
Slider application, once its lifetime timeout expires and YARN has stopped the application.
Destroying a Slider application means cleanup of Slider HDFS state store and ZK paths for
that application. 

Potentially, there will be advanced requirements from the REST-API service and other services
in the future, which will make this feature very handy.
