Ankit Singhal commented on PHOENIX-2862: ---------------------------------------- Hi [~samarthjain], I have created a pull request so that it will be easy for you to review. > Do client server compatibility checks before upgrading system tables > -------------------------------------------------------------------- > > Key: PHOENIX-2862 > URL: https://issues.apache.org/jira/browse/PHOENIX-2862 > Project: Phoenix > Issue Type: Sub-task > Reporter: Ankit Singhal > Assignee: Ankit Singhal > Fix For: 4.8.0 > > Attachments: PHOENIX-2862.patch > > > currently , we allow upgrade of system tables to map to system namespace by > enabling "phoenix.schema.mapSystemTablesToNamespace" config (conjuction with > "phoenix.connection.isNamespaceMappingEnabled") > but we need to ensure following things whenever client connects with above > config:- > 1. Server should be upgraded and check consistency of these properties > between client and server. > 2. If above property does not exists but system:catalog exists, we should not > start creating system.catalog. > 3. if old client connects, it should not create system.catalog again ignoring > the upgrade and start using it. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
