Question

我在我的spark应用程序中遇到此问题，我使用1.6 spark版本，scala 2.10：

17/10/23 14:32:15 ERROR yarn.ApplicationMaster: Uncaught exception:

我读了这个问题，我尝试修改下一个参数而没有结果 --conf spark.yarn.am.waitTime = 6000s

- conf spark.sql.broadcastTimeout = 6000

- conf spark.network.timeout = 600

Answer 1

请删除代码上的setMaster（'local'），因为默认情况下Spark使用EMR中的YARN集群管理器。

Answer 2

如果您尝试在yarn client/cluster上运行Spark作业。不要忘记从代码master中删除.master("local[n]")的配置。

要在纱线上提交火花作业，您需要通过--master yarn --deploy-mode cluster/client。

将master设置为local会导致重复超时异常。

错误yarn.ApplicationMaster：未捕获异常：java.util.concurrent.TimeoutException：期货在100000毫秒后超时
