Change subject: IMPALA-12849: Standby catalogd should reject requests from coordinators ...................................................................... IMPALA-12849: Standby catalogd should reject requests from coordinators In a catalog HA enabled cluster, it's possible that the standby catalogd could receive requests from coordinators in a short window after manual fail-over is triggered since the coordinators may receive the fail-over notification from statestore with delayed time. In this scenarios, the standby catalogd should reject all requests from coordinators so that only one catalogd serving catalog service for the cluster. This patchs checks if the catalog server is active when handling request from clients. Testing: - Added end-to-end unit-test. - Passed core tests.
