uh, because that is not to create a Hive table. How about simplifying the
test case to?
```Scala
test("SPARK-20594: hive.exec.stagingdir was deleted by Hive") {
// Set hive.exec.stagingdir under the table directory without start
with ".".
withSQLConf("hive.exec.stagingdir" -> "./test") {
withTable("test_table") {
sql("CREATE TABLE test_table (key int)")
sql("INSERT OVERWRITE TABLE test_table SELECT 1")
checkAnswer(sql("SELECT * FROM test_table"), Row(1))
}
}
}
```
