---------------------------------
Summary: Do not open transaction for readonly query
Key: HIVE-22016
URL: https://issues.apache.org/jira/browse/HIVE-22016
Project: Hive
Issue Type: Sub-task
Reporter: Daniel Dai
Open/abort/commit transaction would increment transaction id which is a burden
unnecessarily. In addition, it spams the notification log and make CachedStore
(and of cause other components rely on notification log) harder to catch up.
