[jira] [Created] (PHOENIX-7639) Improve error handling in PhoenixMasterObserver

Viraj Jasani created PHOENIX-7639:
-------------------------------------

             Summary: Improve error handling in PhoenixMasterObserver
                 Key: PHOENIX-7639
                 URL: https://issues.apache.org/jira/browse/PHOENIX-7639
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Viraj Jasani


If the cluster is upgraded to Phoenix 5.3 without metadata upgrade, new system tables SYSTEM.CDC_STREAM_STATUS and SYSTEM.CDC_STREAM will not be created yet.

Any region merges or splits with PhoenixMasterObserver coproc hooks can encounter errors as without the system tables, we cannot persist stream partition metadata related to region splits and merges. We need to handle this error.

Moreover, it is important to not miss the updates to SYSTEM.CDC_STREAM table as part of postCompletedSplitRegionAction() and postCompletedMergeRegionsAction(). The purpose of this Jira is to introduce maximum retries possible to make the upserts successful.
