Failed to set the parallel query pool {0} because the parallel query helper service does not exist
Cause
An attempt was made to set a parallel query pool for the service that does not have a parallel query helper service configured or whose configured parallel query helper service would be removed by the '-pqservice' argument.
Action
Issue the command "srvctl modify service -db <database_name> -service <primary_service_name> -pqservice <pq_service_name> -pqpool <pq_pool_name>" to configure parallel query service for the specified parallel query server pool.
