> HiveServer2 currently has a metric for the total number of queries ran since 
> last restart, but it would be useful to also have metrics for number of 
> queries ran for each execution engine. This would improve supportability by 
> allowing users to get a high-level understanding of what workloads had been 
> running on the server.
