>                 URL: https://issues.apache.org/jira/browse/HIVE-19213
>             Project: Hive
>          Issue Type: Bug
>            Reporter: Gopal V
>            Priority: Major
>
> When the query-cache is hit, the ACID TxnManager opens a txn + lock + heartbeats on _dummy_database._dummy_table.
> This is blocking the query-cache from jumping through the fast-paths for transactions.
