Resolution: Duplicate
> Datanode's replication queue full of timeout replication task
> -------------------------------------------------------------

> Key: HDDS-6848
> URL: https://issues.apache.org/jira/browse/HDDS-6848
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Janus Chow
> Assignee: Janus Chow
> Priority: Major
> Labels: pull-request-available
>
> If a datanode crashes, the blocks on the datanode will be added to
> inflightReplication to fulfill the replication factor.
> When the datanode is restarted, the containers don't need to be replicated
> anymore, but the replication commands have been sent to datanodes. If the
> crashed datanodes holds many containers, there will be many replication
> commands which will cause jams on Datanodes's replication queue, and the big
> replication traffic will also cause problems to the whole cluster.
