> 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.
> As explained in
> https://issues.apache.org/jira/browse/YARN-3104?focusedCommentId=14298692&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14298692
> , the AM-RM connection is not re-established so the updated token in the
> client's UGI is never re-sent to the RPC server andRM continues to send the
> token each heartbeat since it cannot be sure whether the client really has
> the new token. Hence the log lines are printed on every heartbeat.
