Basically this point got discussed in earlier comments also, this JIRA is to
track lifetime of an application. Defining lifetime is nothing but overall
execution_time of application from submission time. Application get killed at
any point of time. Basically user is imposing timeout for execution time. Use
case is every 5 minutes he submits a application and user need output with in 5
minutes. Use do not worry for time-consumed on statestore or allocation or any
other which is not user facing also.
Considering each stages of timeout, in future any other timeouts can be added
to ApplicationTimeouts class. ApplicationTimeouts java doc also gives
definition of lifetime.

So if the app is sitting in ACCEPTED state, as per current implementation the
timeout monitor has started, right? If yes, then it does not fully satisfy the
lifetime feature that YARN-4692 is looking for. In that case, we need to
introduce monitor-start-time as a configurable parameter in
ApplicationTimeouts. App submitters should be able to specify it along with the
timeout value. The start time could be a set of relevant app state transition
watermarks, like AppTimeoutsMonitorStartTime.SUBMISSION_TIME,
AppTimeoutsMonitorStartTime.LAUNCH_TIME, etc. 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.
