Hi, [~dakghar]
For me, those seems not to work even in `spark-shell`. Could you add a `show`
at the end? I tested and got the same result in 2.0.0 and current master branch.
{code}
scala> import org.apache.spark.sql.SparkSession
scala> val spark = SparkSession.builder.enableHiveSupport().getOrCreate()
scala> spark.sql("show databases").show
+------------+
|databaseName|
+------------+
| default|
+------------+
scala> spark.stop()
scala> val spark = SparkSession.builder.enableHiveSupport().getOrCreate()
scala> spark.sql("show databases").show
