adding comments to Hive Stats JDBC queries
-------------------------------------------
Key: HIVE-2000
URL: https://issues.apache.org/jira/browse/HIVE-2000
Project: Hive
Issue Type: Improvement
Reporter: Ning Zhang
Assignee: Ning Zhang
Priority: Trivial
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.
