             Summary: Make `ozone debug om compaction-dag` run locally and offline
                 Key: HDDS-12053
                 URL: https://issues.apache.org/jira/browse/HDDS-12053
             Project: Apache Ozone
          Issue Type: Sub-task
            Reporter: Ethan Rose


{{ozone debug om compaction-dag}}, which is the new location of {{ozone debug print-log-dag}} has a few implementation issues:
* The command goes over the network, but writes the resulting graph locally to the server
* The command requires the OM to be online, which may not be the case if it has crashed or we are examining disk state we received from a cluster we cannot access

Like other debug commands, we should make this run only on the disk state present on OM. The OM process may be running while this is happening, but this is not required. This may require moving some snapshot code to common modules.
