Assignee: (was: Jason Fehr)

> Key: IMPALA-13965
> URL: https://issues.apache.org/jira/browse/IMPALA-13965
> Project: IMPALA
> Issue Type: Bug
> Reporter: Jason Fehr
> Priority: Major
> Labels: impala
>
> When an Impala cluster has no executors (e.g. the only nodes in the cluster
> are coordinator, statestored, and catalogd), then user/group admission quotas
> are not applied. Users can submit as many queries as they like. All queries
> are queued with the message "Query queued. Latest queuing reason: Waiting for
> executors to start. Only DDL queries and queries scheduled only on the
> coordinator (either NUM_NODES set to 1 or when small query optimization is
> triggered) can currently run."
> Once executors are added to the cluster, all queued queries run immediately
> even if the number of queries admitted exceeds a user/group admission control
> quota limit.
> Steps to Replicate:
> 1. Start 1 coordinator configured to allow 2 queries for user.
> 2. Submit a query using impala-shell in three separate terminal windows all
> connected to the coordinator.
> 3. Start 1 Impala executor adding it to the existing cluster.
> 4. Once the executor became available, all three queries run at the same time
> and finish within a few hundred milliseconds of each other.
