Jason Lowe created MAPREDUCE-6324: ------------------------------------- Summary: Uber jobs fail to update AMRM token when it rolls over Key: MAPREDUCE-6324 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6324 Project: Hadoop Map/Reduce Issue Type: Bug Components: mr-am Affects Versions: 2.6.0 Reporter: Jason Lowe Assignee: Jason Lowe Priority: Blocker
When the RM rolls a new AMRM master key the AMs are supposed to receive a new AMRM token on subsequent heartbeats between the time when the new key is rolled and when it is activated. This is not occurring for uber jobs. If the connection to the RM needs to be re-established after the new key is activated (e.g.: RM restart or network hiccup) then the uber job AM will be unable to reconnect to the RM. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
