1、scala插件的安装首先在欢迎界面点击Configure，选择plugins如下图所示：下面的第三个图是安装后的所以是uninstall 没有安装的话是 install ，安装成功后，点击OK退出
2、全局JDK和Scala SDK的设置如下图所示
3、新建maven项目:欢迎界面点击Create New Project，在打开的页面左侧边栏中，选择Maven，然后在右侧的Project SDK一项中，查看是否是正确的JDK配置项正常来说这一栏会自动填充的
4、导入spark依赖:<properties> <spark.version>2.4.0</spark.version> <scala.version>2.12</scala.version> </properties> <dependencies> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-core_${scala.version}</artifactId> <version>${spark.version}</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-streaming_${scala.version}</artifactId> <version>${spark.version}</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-sql_${scala.version}</artifactId> <version>${spark.version}</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-hive_${scala.version}</artifactId> <version>${spark.version}</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-mllib_${scala.version}</artifactId> <version>${spark.version}</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.scala-tools</groupId> <artifactId>maven-scala-plugin</artifactId> <version>2.15.2</version> <executions> <execution> <goals> <goal>compile</goal> <goal>testCompile</goal> </goals> </execution> </executions> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.6.0</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.19</version> <configuration> <skip>true</skip> </configuration> </plugin> </plugins> </build>
5、编写sprak代码打印hellow world!import org.apache.spark.sql.{ SparkSession}object SparkHellowWorld { def main(args: Array[String]) { val spark= SparkSession.builder.master("local").appName("WordCountLocal").getOrCreate //如果是打成jar包运行则需要去掉 "local"因为在参数中会指定 spark.sparkContext.makeRDD(Seq("hellow Word!")) .collect().foreach(println(_)) }}按如下图在本地运行
