Since these methods return a Dataset, you can use Dataset API to May you check what your Spark version is in this scenario? According to Hive Tables in the official Spark documentation:. {Row, SaveMode, SparkSession} case class Record (key: Int, value: String) // warehouseLocation은 hive 데이터베이스와 테이블의 기본 위치를 지정합니다. But on local it creates in the current directory. And spark tries to read the table from default /home/user/spark-warehouse location. dir is null (so it is not read from the metastore) and it has to be set manually in the spark session via spark. + it should look something like that: Don't forget to replace the "hive. appName("yourappname") . dir property in hive-site.
