-Re: Job running on YARN gets automatically killed after 10-12 minutes

Is this your custom application and not, say, MapReduce or the distributed shell?
If that is the case, the ApplicationMaster needs to constantly ping the ResourceManager so that RM can know that it is alive. This is done by simply doing an allocate(..) call that is part of the scheduler API. This you should do irrespective of whether you have any new container requests or not.
The default liveliness interval is 10 mins, so you are seeing that your app is getting killed roughly after that much time.
