beliefer edited a comment on issue #23841: [SPARK-26936][SQL] Fix bug of insert overwrite local dir and inconsistent behavior with Hive URL: https://github.com/apache/spark/pull/23841#issuecomment-467742406 I have run these SQL you provided on local[*] deploy mode and still appear inconsistent behavior too. The spark version to test is 2.3.0. ``` ls /tmp/noexistdir ls: cannot access /tmp/noexistdir: No such file or directory scala> sql("""create table t(c0 int, c1 int)""") res0: org.apache.spark.sql.DataFrame = [] scala> spark.table("t").explain == Physical Plan == HiveTableScan [c0#5, c1#6], HiveTableRelation `default`.`t`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [c0#5, c1#6] scala> sql("""insert into t values(1, 1)""") scala> sql("""select * from t""").show +---+---+ | c0| c1| +---+---+ | 1| 1| +---+---+ scala> sql("""insert overwrite local directory '/tmp/noexistdir/t' select * from t""") res1: org.apache.spark.sql.DataFrame = [] ls /tmp/noexistdir/t/ /tmp/noexistdir/t vi /tmp/noexistdir/t 1 ``` '/tmp/noexistdir/t' is not a directory but a file. Normally, temp path has result file and '_SUCCESS' file. I doubt result file cover the '_SUCCESS' file by code as follows: ` fs.listStatus(tmpPath).foreach { tmpFile => fs.rename(tmpFile.getPath, writeToPath) }`
