@@ -353,6 +358,13 @@ To replace data in the table with the result of a query,
use `INSERT OVERWRITE`.
The partitions that will be replaced by `INSERT OVERWRITE` depends on Spark's
partition overwrite mode and the partitioning of a table.
+!!! Warning
+ Spark 3.0.0 has a correctness bug that affects dynamic `INSERT OVERWRITE`
with hidden partitioning, [SPARK-32168][spark-32168].
+ For tables with [hidden partitions](../partitioning), wait for Spark 3.0.1.
