Aravindan Vijayan updated HDDS-4183: ------------------------------------ Description: HDDS-2939 makes fundamental changes to how OM writes & reads its metadata. Since this is about as big a layout change as can be, we have to make sure this is properly managed through the upgrade flow. In addition to upgrades, we should support downgrades from pre-finalized state of OM. cc [~rakeshr] / [~msingh] > Support backward compatible upgrade to a version with key prefix management. > ---------------------------------------------------------------------------- > > Key: HDDS-4183 > URL: https://issues.apache.org/jira/browse/HDDS-4183 > Project: Hadoop Distributed Data Store > Issue Type: Sub-task > Components: Ozone Manager > Reporter: Aravindan Vijayan > Assignee: Aravindan Vijayan > Priority: Major > Fix For: 1.1.0 > > > HDDS-2939 makes fundamental changes to how OM writes & reads its metadata. > Since this is about as big a layout change as can be, we have to make sure > this is properly managed through the upgrade flow.
