Summary: Handle failed coordinators in admissiond
Key: IMPALA-10594
URL: https://issues.apache.org/jira/browse/IMPALA-10594
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Affects Versions: Impala 4.0
Reporter: Thomas Tauber-Marshall
Assignee: Thomas Tauber-Marshall
Currently, when a coordinator fails the admissiond will not detect this and the
resources being used by queries on that coordinator will never be released. We
should monitor the cluster membership through the statestore and have the
admissiond detect failed coordinators and cancel all of their queries.
