Spark执行程序登录YARN

我正在Cloudera集群上以YARN客户端模式启动分布式Spark应用程序.过了一段时间,我在Cloudera Manager上看到了一些错误.一些执行器断开连接,系统地发生这种情况.我想调试该问题,但YARN没有报告内部异常.

Exception from container-launch with container ID: container_1417503665765_0193_01_000003 and exit code: 1
ExitCodeException exitCode=1:

如何查看异常的堆栈跟踪？似乎YARN仅报告应用程序异常退出.有没有办法在YARN配置中查看spark executor日志？
