[jira] [Created] (HDDS-8658) ReplicationManager: Change default command timeout to 10 minutes

             Summary: ReplicationManager: Change default command timeout to 10 minutes
                 Key: HDDS-8658
                 URL: https://issues.apache.org/jira/browse/HDDS-8658
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: SCM
            Reporter: Stephen O'Donnell
            Assignee: Stephen O'Donnell


In Replication Manager, a deadline is set on commands sent to a datanode. If the command has not completed within the timeout, RM assumes it is lost and will schedule a new command to another random node.

Right now the default is set to 30 minutes as the legacy RM scheduled a lot of work onto the DNs and it could take a long time to complete. The new RM throttles the work sent, so a large queue on the DNs should not be possible.

We should change the default event timeout to 10 minutes instead of 30.
