------------------------------------------------------------
Actually it is recommended to use another hive-site.xml for spark rather than
share the same hive-site.xml. You need to specify hive.execution.engine=mr in
your hive-site.xml used by spark.

> Key: SPARK-15779
> URL: https://issues.apache.org/jira/browse/SPARK-15779
> Project: Spark
> Issue Type: Bug
> Components: Spark Shell, Spark Submit, SQL
> Affects Versions: 1.6.1
> Environment: Hadoop 2.7.2, Spark 1.6.1, Hive 2.0.1, Tez 0.8.3
> Reporter: Alexandre Linte
>
> By default, Hive uses MapReduce as its default execution engine. Since Hive
> 2.0.0, MapReduce is deprecated.
> To avoid this deprecation, I decided to use Tez instead of MapReduce as the
> default execution engine. Unfortunately, this choice had an impact on Spark.
> Now when I start Spark the SQL context fails with the following error:
> {noformat}
