使用Spark setMaster（＆＃34; spark：//127.0.0.1：7077＆＃34;）发生错误

标签： java servlets apache-spark

我写了一个java web程序来调用我的计算机上安装的独立spark。如果我按照以下方式进行配置，它会顺利运行。

String input = "hdfs://127.0.0.1:9000/plane/2008c.csv";
SparkConf conf = new SparkConf().setAppName("org.spark.flight").setMaster("local").set("spark.driver.allowMultipleContexts", "true");

但是当我改变代码时发生了错误。

String input = "hdfs://127.0.0.1:9000/plane/2008c.csv";
SparkConf conf = new SparkConf().setAppName("org.spark.flight").setMaster("spark://127.0.0.1:7077").set("spark.driver.allowMultipleContexts", "true");

错误：

出了什么问题？当我向spark集群服务器提交代码时，无论我使用setMaster（＆＃34; spark：// IP：PORT＆＃34;）还是setMaster（＆＃34; local＆＃34;），都会发生错误。< / p>

我看到类似的问题，当群集上的Spark版本与我的项目pom.xml上的驱动程序依赖版本不同。 尝试找出您在群集和驱动程序上使用的Spark版本。
