Lavkesh Lahngir created YARN-4750: ------------------------------------- Summary: App metrics may not be correct when and app is recovered Key: YARN-4750 URL: https://issues.apache.org/jira/browse/YARN-4750 Project: Hadoop YARN Issue Type: Bug Reporter: Lavkesh Lahngir Assignee: Lavkesh Lahngir
App metrics(rather app attempt metrics) like Vcore-seconds and MB-seconds are saved in the state store when there is an attempt state transition. Values for running attempts will be in memory and will not be saved when there is an RM restart/failover. For recovered app metrics value will be reset. In that case, the value will be incomplete. Was this intentional or have we not found a correct way to fix it ? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
