@rakanchiSpark currently doesn't support "insert into feature", you need to create dataframe and append to the table.
var data = sqlContext.createDataFrame(Seq(("ZZ", "m:x", 34.0))).toDF("pv", "metric", "value")
data.show()
data.write.mode("append").saveAsTable("results_test_hive")
println(sqlContext.sql("select * from results_test_hive").count())
