> AMRMClient logging on every heartbeat to track updation of AM RM token causes
> too many log lines to be generated in AM logs

> Key: YARN-8210
> URL: https://issues.apache.org/jira/browse/YARN-8210
> Project: Hadoop YARN
> Issue Type: Bug
> Components: yarn
> Affects Versions: 2.9.0, 3.0.0-alpha1
> Reporter: Suma Shivaprasad
> Assignee: Suma Shivaprasad
> Priority: Major
>
> YARN-4682 added logs to track when AM RM token is updated for debuggability
> purposes. However this is printed on every heartbeat and could cause the AM
> logs to be flooded with this whenever RM's Master key is rolled over
> especially if its a long running AM. Hence proposing to remove this log line
