Resolution: Implemented
> Set RM default deadline to 12 minutes and the datanode offset to 6 minutes

> Key: HDDS-12135
> URL: https://issues.apache.org/jira/browse/HDDS-12135
> Project: Apache Ozone
> Issue Type: Improvement
> Components: SCM
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.0.0
>
>
> We recently found that delete commands can run for a long time once picked
> off the queue, and the default of a 10 minute deadline on SCM and 30 seconds
> less deadline on the datanodes can result in currently running commands being
> seen as expired in SCM.
> This PR is to make the defaults less aggressive - giving a SCM / RM timeout
> of 12 minutes and a datanode timeout of 6 minutes. That way, there is longer
> for commands to be processed before RM will resend them.
> With the throttling that RM employs, there should not be a large number of
> commands on the queue anyway, as the goal of RM is to schedule only the
> number of commands which can be processed in a heartbeat or two.
