我的火花版本是1.6.2并且在纱线上运行。
驱动器容器的日志报告SUCCEEDED，如下所示：
16/11/17 17:25:56 INFO ApplicationMaster: Final app status: SUCCEEDED, exitCode: 0
16/11/17 17:25:56 INFO ApplicationMaster: Unregistering ApplicationMaster with SUCCEEDED
但是，一个执行程序容器的日志记录ERROR：
16/11/17 17:25:56 WARN CoarseGrainedExecutorBackend: An unknown (xxx-xxx-xxx-xxx:xxxx) driver disconnected.
16/11/17 17:25:56 ERROR CoarseGrainedExecutorBackend: Driver xxx-xxx-xxx-xxx:xxxx disassociated! Shutting down.
我认为工作成功，因为输出结果符合预期。
但我想知道为什么错误被抛出以及这项工作是否真的成功了。
我从纱线NodeManager的日志中找到更多信息：
WARN org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor: Exception from container-launch with container ID: container_xxxxxxxxx and exit code: 1

有人遇到同样的问题吗？
感谢。
