Dongjoon Hyun updated SPARK-16370: ---------------------------------- Description: Currently, some queries having side effects like `Command`, `InsertIntoTable`, and `CreateTableUsingAsSelect` are executed eagerly. However, it matches `UNION` queries some cases. This issue prevents `UNION` eager execution except `MULTI-INSERT` syntax. was: Currently, some queries having side effects like `Command`, `InsertIntoTable`, and `CreateTableUsingAsSelect` are executed eagerly. However, for `UNION` queries, they are executed only in `UNION ALL` queries with all children having side effects. This issue executes them eagerly for both `UNION` and `UNION ALL` queries if one of their children has side effects. Summary: Union queries should not be executed eagerly (was: Union queries with side effects should be executed eagerly) > Union queries should not be executed eagerly > -------------------------------------------- > > Key: SPARK-16370 > URL: https://issues.apache.org/jira/browse/SPARK-16370 > Project: Spark > Issue Type: Bug > Components: SQL > Reporter: Dongjoon Hyun > > Currently, some queries having side effects like `Command`, > `InsertIntoTable`, and `CreateTableUsingAsSelect` are executed eagerly. > However, it matches `UNION` queries some cases.
