Connecting to Hive using Spark-SQL

Question

I am running hive queries using Spark-SQL. I made a hive context object

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

Then when I am trying to run the command:

hiveContext.sql("use db_name");

OR

hiveContext.hiveql("use db_name");

It doesnt work. It says database not found. When I try to run

val db = hiveContext.hiveql("show databases");
db.collect.foreach(println);

It prints nothing. Just prints [default] .

Any help would be appreciated.

Answer 1

 hiveContext.sql("SELECT * FROM database.table")
