Description
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.
