将应用程序提交到spark集群：错误本地类不兼容

时间：2016-04-23 17:36:33

标签： java maven hadoop apache-spark

我写了一个java web应用程序，它在我自己的计算机上安装的独立spark上工作得很好。但是当我提交给spark集群服务器时，发生了错误。

服务器端集群的环境：
Java：1.8.0_74
Hadoop：2.6.0
Spark：1.6.1
斯卡拉：2.10.5

我自己的电脑环境 Java：1.8.0_20
Hadoop：2.6.0
Spark：1.6.1
斯卡拉：2.10.5

错误如下：

Spark 1.6.1打包版本的servlet API和一个打包到你的jar中是不同的。 Spark使用

  

org.eclipse.jetty.orbit»javax.servlet 3.0.0.v201112011016

http://mvnrepository.com/artifact/org.apache.spark/spark-core_2.10/1.6.1

如果可能，请尝试不将Servlet API打包到jar中

<dependency>
   <groupId>org.eclipse.jetty.orbit</groupId>
   <artifactId>javax.servlet</artifactId>
   <version>3.0.0.v201112011016</version>
   <scope>provided</scope>
 </dependency>
