--------------------------------------
Summary: 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
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.
