> URL: https://issues.apache.org/jira/browse/HDDS-8187
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: SCM
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.4.0
>
>
> In order to keep a consistent count of the number of pending replicate and
> delete commands, ReplicationManager should send commands to the datanode via
> the nodeManager.addDatanodeCommand() method rather than publishing them to
> the event queue.
> At the moment, the commands goto the event queue, where they are picked up by
> NodeManager and added to the datanode command queue. As we are using the
> counts in the command queue to determine how many commands are pending, the
> indirection provided by the event queue makes it difficult to keep a
> consistent count without excessive effort.
> There is also no further processing done on the commands in the event queue,
> they simply go RM -> Event Queue -> Node Manager -> Command Queue.
> This change makes RM send the commands to nodeManager directly.
