How to connect Spark to a remote Hive server?

Can anyone help me in understanding how I can load data from Hive server which is installed remotely into Spark data frame. Do I need a hive jdbc connector?

Use org.apache.spark.sql.hive.HiveContext & you can perform query on Hive.

But I would suggest you to connect Spark to HDFS & perform analytics over the stored data. It would be much more efficient that connecting Spark with Hive and then performing analysis over it.

JDBC is not required here.

Create a hive SQLContext as below , this works for me 

val conf = new org.apache.spark.SparkConf().setAppName("hive app")

val sc = new org.apache.spark.SparkContext(conf)

val sqlContext = new org.apache.spark.sql.hive.HiveContext(sc)

val df1 = sqlContext.sql(s"use $dbname");

val dfUnion1 = sqlContext.sql(s"Select * from table_name");
