Once datanode is started, it will need 90s before > transited to {{Heartbeat}} state, such a long lag is not necessary. Propose > to improve the logic of time interval handling, it seems only the heartbeat > task needs to be scheduled in {{OZONE_SCM_HEARTBEAT_INTERVAL_SECONDS}} > interval, rest should be done without any lagging. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
