-------------------------------------
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.
