> Stats gathering could issue a large number of JDBC queries to stats publisher
> and aggregator. In a shared DB environment, it's hard to tell which SQL
> statements are contributed by Hive stats gathering tasks. It would be easier
> to identify these workload by adding SQL comments that identifies the source
> of the query.
