dongjoon-hyun edited a comment on issue #28232: [SPARK-31459][SQL]fix insert overwrite directory target path is an existing file URL: https://github.com/apache/spark/pull/28232#issuecomment-615548088 Ur, @mcdull-zhang . When I try at Apache Spark 3.0.0-RC1 and 2.4.5, I get the followings. For me, the current Apache Spark behavior looks correct to me. **3.0.0-RC1** ```scala scala> spark.version res1: String = 3.0.0 scala> sql("INSERT OVERWRITE LOCAL DIRECTORY '/tmp/p1' STORED AS ORC SELECT 1").show java.lang.RuntimeException: Cannot create staging directory 'file:/tmp/p1/.hive-staging_hive_2020-04-18_03-27-45_173_5810881255552839519-1': Parent path is not a directory: file:/tmp/p1 ``` **2.4.5** ``` scala> spark.version res1: String = 2.4.5 scala> sql("INSERT OVERWRITE LOCAL DIRECTORY '/tmp/p1' STORED AS ORC SELECT 1").show java.lang.RuntimeException: Cannot create staging directory 'file:/tmp/p1/.hive-staging_hive_2020-04-18_03-36-22_566_4239182152715274882-1': Parent path is not a directory: file:/tmp/p1 ``` Could you give me an example how you got the final operation incorrect result? > When using the insert overwrite directory syntax, if the target path is an existing file, the final operation result is incorrect.
