Hi Jerry,
I am having trouble with this. May be something wrong with my import or version
etc.
scala> import org.apache.spark.sql._;import org.apache.spark.sql._
scala> val hiveContext = new
org.apache.spark.sql.hive.HiveContext(sc)<console>:24: error: object hive is
not a member of package org.apache.spark.sql val hiveContext = new
org.apache.spark.sql.hive.HiveContext(sc)
^Here is what I see for autocompletion:
scala> org.apache.spark.sql.Row SQLContext SchemaRDD
SchemaRDDLike apicatalyst columnar execution package

Hi Sameer,
The blog post you referred to is about Spark SQL. I don't think the intent of
the article is meant to guide you how to read data from Hive via Spark SQL. So
don't worry too much about the blog post.
The programming guide I referred to demonstrate how to read data from Hive
using Spark SQL. It is a good starting point.
Best Regards,
Jerry

Hi Michael,Thanks. I am not creating HiveContext, I am creating SQLContext. I
am using CDH 5.1. Can you please let me know which conf/ directory you are
talking about?

In particular, have you put your hive-site.xml in the conf/ directory? Also,
are you creating a HiveContext instead of a SQLContext?

Hi All,I am trying to load data from Hive tables using Spark SQL. I am using
spark-shell. Here is what I see:
val trainingDataTable = sql("""SELECT prod.prod_num, demographics.gender,
demographics.birth_year, demographics.income_group FROM prod p JOIN
demographics d ON d.user_id = p.user_id""")
14/07/25 14:18:46 INFO Analyzer: Max iterations (2) reached for batch
MultiInstanceRelations14/07/25 14:18:46 INFO Analyzer: Max iterations (2)
reached for batch CaseInsensitiveAttributeReferences
java.lang.RuntimeException: Table Not Found: prod.
I have these tables in hive. I used show tables command to confirm this. Can
someone please let me know how do I make them accessible here?
