### What changes were proposed in this pull request? Currently, we have a bug when we specify `IF NOT EXISTS` in `INSERT OVERWRITE` data source tables. For example, given a query: ```SQL INSERT OVERWRITE TABLE $tableName partition (b=2, c=3) IF NOT EXISTS SELECT 9, 10 ``` we will get the following error: ``` unresolved operator 'InsertIntoTable Relation[a#425,d#426,b#427,c#428] parquet, Map(b -> Some(2), c -> Some(3)), true, true;; 'InsertIntoTable Relation[a#425,d#426,b#427,c#428] parquet, Map(b -> Some(2), c -> Some(3)), true, true +- Project [cast(9#423 as int) AS a#429, cast(10#424 as int) AS d#430] +- Project [9 AS 9#423, 10 AS 10#424] +- OneRowRelation$ ``` This PR is to fix the issue to follow the behavior of Hive serde tables > INSERT OVERWRITE will overwrite any existing data in the table or partition unless IF NOT EXISTS is provided for a partition ### How was this patch tested? Modified an existing test case Author: gatorsmile <gatorsmile@gmail.com> Closes #18050 from gatorsmile/insertPartitionIfNotExists. |
