Naganarasimha G R resolved YARN-2487.
-------------------------------------
Resolution: Won't Fix
Seems like to an extent this issue can be resolved using YARN-3813 and its
subjira's but [~nijel], [~rohithsharma] , [~jianhe] & [~wangda], please check
weather we need to support the scenario of timing out only in the case app is
not running. Based on the above scenario thought it might be required.
Currently closing this jira.
> Need to support timeout of AM When no containers are assigned to it for a
> defined period

> Key: YARN-2487
> URL: https://issues.apache.org/jira/browse/YARN-2487
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Reporter: Naganarasimha G R

>
> There are some scenarios where AM will not get containers and indefinitely
> waiting. We faced one such sceanrio which makes the applications to get hung
> :
> Consider a cluster setup which has 2 NMS of each 8GB resource,
> And 2 applications(MR2) are launched in the default queue where in each AM is
> taking 2 GB each.
> Each AM is placed in each of the NM. Now each AM is requesting for container
> of 7Gb mem resource .
> As in each NM only 6GB resource is available both the applications are hung
> forever.
> To avoid such scenarios i would like to propose
> generic timeout feature for all AM's in yarn, such that if no containers are
> assigned for an application for a defined period than yarn can timeout the
> application attempt.
> Default can be set to 0 where in RM will not timeout the app attempt and user
> can set his own timeout when he submits the application
