errose28 opened a new pull request #1798: URL: https://github.com/apache/ozone/pull/1798
## What changes were proposed in this pull request? When an OM is put in prepare mode, a marker file is written to disk so that it remains in prepare mode upon restart. After an OM has been upgraded, it can be restarted with a --upgrade flag to automatically delete the marker file and take the OM out of prepare mode. This patch incorporates work in progress changes from HDDS-4610 to make sure that the commit transaction after prepare updates the transaction index in the OM DB, so it matches the index of the prepare marker file when the OM comes back up. ## What is the link to the Apache JIRA HDDS-4645 Please replace this section with the link to the Apache JIRA) Acceptance test added. The added test uses a similar approach to the existing *upgrade* acceptance test to restart the OMs. All containers in the cluster write their state to mounted volumes, and nodes are restarted by restarting their containers. These restarted containers have the previous on disk state still persistent in the volume when it is mounted on restart. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
