> Scenario
> =======
> 1. RM HA and 5 NMs available in cluster and are working fine
> 2. Add one more NM to the same cluster but RM /etc/hosts not updated.
> 3. Submit application to the same cluster
> If Am get allocated to the newly added NM the *application attempt will get
> stuck for ever*.User will not get to know why the same happened.
> Impact
> 1.RM logs gets overloaded with exception
> 2.Application gets stuck for ever.
> Handling suggestion YARN-261 allows for Fail application attempt .
> If we fail the same next attempt could get assigned to another NM.
