本文为您介绍Spark-1.x依赖的配置以及Spark-1.x相关示例。

配置Spark-1.x的依赖

通过MaxCompute提供的Spark客户端提交应用，需要在 pom.xml文件中添加以下依赖。 
<properties>
    <spark.version>1.6.3</spark.version>
    <cupid.sdk.version>3.3.3-public</cupid.sdk.version>
    <scala.version>2.10.4</scala.version>
    <scala.binary.version>2.10</scala.binary.version>
</properties>
<dependency>
    <groupId>org.apache.spark</groupId>
    <artifactId>spark-core_${scala.binary.version}</artifactId>
    <version>${spark.version}</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.apache.spark</groupId>
    <artifactId>spark-sql_${scala.binary.version}</artifactId>
    <version>${spark.version}</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.apache.spark</groupId>
    <artifactId>spark-mllib_${scala.binary.version}</artifactId>
    <version>${spark.version}</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.apache.spark</groupId>
    <artifactId>spark-streaming_${scala.binary.version}</artifactId>
    <version>${spark.version}</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>com.aliyun.odps</groupId>
    <artifactId>cupid-sdk</artifactId>
    <version>${cupid.sdk.version}</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>com.aliyun.odps</groupId>
    <artifactId>hadoop-fs-oss</artifactId>
    <version>${cupid.sdk.version}</version>
</dependency>
<dependency>
    <groupId>com.aliyun.odps</groupId>
    <artifactId>odps-spark-datasource_${scala.binary.version}</artifactId>
    <version>${cupid.sdk.version}</version>
</dependency>
<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-library</artifactId>
    <version>${scala.version}</version>
</dependency>
<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-actors</artifactId>
    <version>${scala.version}</version>
</dependency>
上述代码中Scope的定义如下：
  • spark-core、spark-sql等所有Spark社区发布的包，使用providedScope。
  • odps-spark-datasource使用默认的compileScope。

WordCount示例
