Answer 1

For Maven projects, after you add the HIVE dependency, just click the "Update Project" by right-clicking on your project -> Maven -> Update Project. This should solve the issue.

Answer 2

Because of hive's dependencies it is not compiled into the spark binary by default you have to build it yourself. Quote from the website

However, since Hive has a large number of dependencies, it is not included in the default Spark assembly. In order to use Hive you must first run sbt/sbt -Phive assembly/assembly (or use -Phive for maven).

Answer 3

Using sbt:

You have to include spark-hive in your dependencies.

To do so add the following line in your .sbt file:

libraryDependencies += "org.apache.spark" %% "spark-hive" % "1.5.0"

Answer 4

Here's an example maven dependency

<dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-hive_${scala.tools.version}</artifactId>
        <version>${spark.version}</version>
</dependency>

--- for those who need to know how to set the properties in POM, below is an example

<properties>
        <maven.compiler.source>1.7</maven.compiler.source>
        <maven.compiler.target>1.7</maven.compiler.target>
        <encoding>UTF-8</encoding>
        <scala.tools.version>2.10</scala.tools.version>
        <scala.version>2.10.4</scala.version>
        <spark.version>1.5.0</spark.version>
</properties>
