Summary: 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 Assignee: Naganarasimha G R There are some scenarios where AM will not get containers and indefinetely 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 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 to propose generic timeout feature for all AM's @ the yarn side 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
