---------------------------------------
Summary: Add cluster id to the membership and request-queue topic
names
Key: IMPALA-13208
URL: https://issues.apache.org/jira/browse/IMPALA-13208
Project: IMPALA
Issue Type: New Feature
Components: Backend
Reporter: Quanlong Huang
Assignee: Quanlong Huang
Coordinators subscribe to 3 statestore topics: catalog-update,
impala-membership and impala-request-queue. The last two topics are about query
scheduling. To separate the cluster or share catalogd and statestore across
Impala clusters, we can add the cluster id to these two topic names. Impalads
are only visible to each other inside the same cluster (i.e. using the same
cluster id). Queries won't be scheduled across clusters.
