Question

我正在使用 spark-1.5.0-cdh5.6.0 。尝试过示例应用程序（scala）命令是：

> spark-submit --class com.cloudera.spark.simbox.sparksimbox.WordCount --master local /home/hadoop/work/testspark.jar

出现以下错误：

 ERROR SparkContext: Error initializing SparkContext.

Answer 1

Spark有一个名为＆＃34;历史服务器的功能＆＃34;它允许您在SparkContext死后浏览历史事件。通过将spark.eventLog.enabled设置为true来设置此属性。

您有两个选项，可以通过spark.eventLog.dir配置值指定存储事件日志的有效目录，或者如果您不需要，只需将spark.eventLog.enabled设置为false它

您可以在Spark Configuration页面阅读更多相关内容。
