----------------------------------------------
Summary: Implement fault tolerance for the admission control
service
Key: IMPALA-9976
URL: https://issues.apache.org/jira/browse/IMPALA-9976
Project: IMPALA
Issue Type: Sub-task
Components: Distributed Exec
Reporter: Thomas Tauber-Marshall
If the new admission control daemon fails, it would be good to be able to
recover gracefully.
Most of the admission control state is already stored in the statestore, so it
should be possible to launch a new admission control daemon and have it catch
up by retrieving everything from the statestore. Already running queries should
not be affected.
