Question

我在独立群集上运行spark应用程序时遇到问题。（我使用spark 1.1.0版本）。我通过命令成功运行主服务器：

bash start-master.sh

然后我按命令运行一个工人：

bash spark-class org.apache.spark.deploy.worker.Worker spark://fujitsu11:7077

在主人的网络用户界面：

http://localhost:8080

我知道，主人和工人正在跑步。

然后我从Eclipse Luna运行我的应用程序。我通过命令

成功连接到群集

JavaSparkContext sc = new JavaSparkContext("spark://fujitsu11:7077", "myapplication");

在该应用程序工作之后，但是当程序实现以下代码时：

 JavaRDD<Document> collectionRdd = sc.parallelize(list);

崩溃时出现以下错误消息：

我google了很多但我不知道什么是错的... 我在这里找到了类似的讨论：

https://github.com/datastax/spark-cassandra-connector/issues/187

但它并没有解决我的问题...

有人知道什么是错的？

谢谢。

Answer 1

为了解决此问题的其他人的利益：

由于火花连接器与使用的火花版本不匹配，我遇到了同样的问题。 Spark为1.3.1，连接器为1.3.0，出现了相同的错误消息：

org.apache.spark.SparkException: Job aborted due to stage failure:
  Task 2 in stage 0.0 failed 4 times, most recent failure: Lost 
  task 2.3 in stage 0.0

在SBT中更新依赖性解决了这个问题。

Answer 2

找到一种使用IDE / Maven

运行它的方法

创建一个Fat Jar（包含所有依赖项的一个）。为此使用Shade插件。示例pom：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <filters>
            <filter>
                <artifact>*:*</artifact>
                <excludes>
                    <exclude>META-INF/*.SF</exclude>
                    <exclude>META-INF/*.DSA</exclude>
                    <exclude>META-INF/*.RSA</exclude>
                </excludes>
            </filter>
        </filters>
    </configuration>
    <executions>
        <execution>
            <id>job-driver-jar</id>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <shadedArtifactAttached>true</shadedArtifactAttached>
                <shadedClassifierName>driver</shadedClassifierName>
                <transformers>
                    <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
                    <!--
                    Some care is required:
                    http://doc.akka.io/docs/akka/snapshot/general/configuration.html
                    -->
                    <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                        <resource>reference.conf</resource>

                    <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <mainClass>mainClass</mainClass>
                    </transformer>
                </transformers>
            </configuration>
        </execution>
        <execution>
            <id>worker-library-jar</id>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <shadedArtifactAttached>true</shadedArtifactAttached>
                <shadedClassifierName>worker</shadedClassifierName>
                <transformers>
                    <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
                </transformers>
            </configuration>
        </execution>
    </executions>
</plugin>

现在我们必须将已编译的jar文件发送到集群。为此，请在spark配置中指定jar文件，如下所示：

SparkConf conf = new 。SparkConf（）setAppName（ “APPNAME”）.setMaster（ “火花：//机器：7077”）.setJars（新 String [] {“target / appName-1.0-SNAPSHOT-driver.jar”}）;

运行mvn clean包以创建Jar文件。它将在目标文件夹中创建。
使用IDE或使用maven命令运行：

mvn exec：java -Dexec.mainClass =“className”

这不需要spark-submit。只需记住在运行

如果您不想硬编码jar路径，可以执行以下操作：

在配置中，写：

SparkConf conf = new SparkConf（） .setAppName（ “APPNAME”） .setMaster（ “火花：//机器：7077”） .setJars（JavaSparkContext.jarOfClass（this.getClass（）））;

创建胖jar（如上所示）并在运行package命令后使用maven运行：

java -jar target / application-1.0-SNAPSHOT-driver.jar

这将从加载类的jar中获取jar。

Answer 3

我遇到了相同的错误消息，在我的情况下，我的 rdd 是空的，并且尝试针对它执行聚合任务。

在此列出此案例以方便其他遇到此错误消息的人： Job aborted due to stage failure: Task 9 in stage 24.0 failed 4 times

下面提供的链接中的建议有所帮助。 “.. rdd 变空了。空指针异常表示尝试针对空值执行聚合任务。检查您的数据是否为空，其中不应该存在空值，尤其是在聚合主题的那些列上” https://community.cloudera.com/t5/Support-Questions/PySpark-failuer-spark-SparkException-Job-aborted-due-to/td-p/171147
