我有一些问题。我使用SparkSession创建代码spark，iam在SparkSql库中找不到SparkSession。所以iam不能运行代码spark。 Iam问什么是在Spark库中查找SparkSession的版本。我给代码pom.xml。

I have some problem. I create code spark with SparkSession, iam get trouble SparkSession not find in library SparkSql. So iam can't run code spark. Iam question what is version to find SparkSession in library Spark. I give code pom.xml.

谢谢。

Thanks.

you need both core and SQL artifacts

    <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>
