-----------------------------------
Summary: Unify cluster membership management in the backend
Key: IMPALA-8460
URL: https://issues.apache.org/jira/browse/IMPALA-8460
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 3.3.0
Reporter: Lars Volker
Assignee: Lars Volker
We currently subscribe to the cluster-membership statestore topic in both the
ImpalaServer and the Scheduler. Updates are then also propagated to the
Frontend. Additionally the Scheduler has its own representation of the local
backend descriptor, which is not kept in sync with the one in the Impala server.
To make cluster-membership and the interactions with the statestore easier to
reason about, we should pull all membership handling in to a single place.
