> Temp tables shouldn't be locked

> Key: HIVE-12996
> URL: https://issues.apache.org/jira/browse/HIVE-12996
> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Affects Versions: 2.0.0
> Reporter: Wei Zheng

> Internally, INSERT INTO ... VALUES statements use temp table to accomplish
> its functionality. But temp tables shouldn't be stored in the metastore
> tables for ACID, because they are by definition only visible inside the
> session that created them, and we don't allow multiple threads inside a
> session. If a temp table is used in a query, it should be ignored by lock
> manager.
