-----------------------------------------
bq. can you clarify the definition of lifetime in the API
Lifetime of an application is nothing but overall time at which application has
run. It includes sum of *RMStateStore(connection time + retry time + ... )+
Scheduler allocation delay + container run time*. In other words it is
execution_lifetime as Vinod mentioned.
bq. But some apps will need to distinguish {{queue_timeout}} from
{{execution_lifetime}}. Can we distinguish those?
In general case, RMStateStore time will be very less may be less than seconds.
Most of the time spent on either allocation-delay or container-run-time. I
think this need not to be handle separately.
bq. Obviously one of the followup challenges is to clearly define where queuing
starts/ends & execution starts/ends.
IAC, to go ahead with queue_timeout, then time can be from Attempt
SUBMITTED/SCHEDULED to Attempt_removed_from_scheduler. Thoughts?

> This JIRA intend to provide a lifetime monitor service.
> The service will monitor the applications where the life time is configured.
> If the application is running beyond the lifetime, it will be killed.
> The lifetime will be considered from the submit time.
> The thread monitoring interval is configurable.
