> 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.
