Code Spark with SparkSession.

   import org.apache.spark.SparkContext 

   val conf = SparkSession.builder
  .master("local")
  .appName("testing")
  .enableHiveSupport()  // <- enable Hive support.
  .getOrCreate()

回答1:

you need both core and SQL artifacts

<repositories>
    <repository>
        <id>cloudera</id>
        <url>https://repository.cloudera.com/artifactory/cloudera-repos/</url>
    </repository>
</repositories>
<dependencies>
    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-core_2.11</artifactId>
        <version>2.0.0-cloudera1-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-sql_2.11</artifactId>
        <version>2.0.0-cloudera1-SNAPSHOT</version>
    </dependency>
</dependencies>

You need Spark 2.0 to use SparkSession. It's available in Maven central snapshot repository as for now:

groupId = org.apache.spark
artifactId = spark-core_2.11
version = 2.0.0-SNAPSHOT

The same version have to be specified for other Spark artifacts. Note, that 2.0 is still in beta and expected to be stable in about a month, AFAIK.

Update. Alternatively, you can use Cloudera fork of Spark 2.0:

groupId = org.apache.spark
artifactId = spark-core_2.11
version = 2.0.0-cloudera1-SNAPSHOT

Cloudera repository has to be specified in your Maven repositories list:

<repository>
   <id>cloudera</id>
   <url>https://repository.cloudera.com/artifactory/cloudera-repos/</url>
</repository>
