> Currently, Apache Livy relies entirely on the client request payload to
> determine which YARN queue a session should be submitted to. If a client
> submits a session creation request without explicitly defining the
> {{"queue"}} parameter, Livy passes a null or empty configuration to Spark,
> causing the application to fall back to the Hadoop cluster's global default
> YARN queue (usually {{{}default{}}}).
> This creates a limitation for multi-tenant cluster administrators.
> Administrators often need to enforce a specific default YARN queue
> exclusively for all Livy-generated workloads (e.g., a queue named
> {{{}livy{}}}), without relying on end-users to remember to pass the parameter
> manually in every REST API request payload.
