Rohith Sharma K S commented on YARN-6600:
-----------------------------------------

High level changes on the patch
# introduced CS scheduler config key to load max lifetime value. 
# On submission, RMAppImpl validate for scheduler max lifetime value and sets accordingly.
# On update, RMAppManager validate for scheduler max lifetime value. If updated value exceeds queue max lifetime value than cut off to scheduler max queue lifetime and send new timeout value in response. 
# Changed update response proto that carries new timeout value in iso8601 format. 
# tests are modified accordingly

> Enhance default lifetime of application at LeafQueue level.

> Setting timeout at LeafQueue level allows admin to control from bad apps which uses most of the resources for all the time. 
> Example : Any application submitted to particular queue i.e QUEUE-1 should not  run more than N hours. Even user set lifetime as N+1 hour, the application will be killed after N hours.
