我成功地在三个节点上安装了spark。我可以访问spark web ui，发现每个工作节点和主节点都处于活动状态。
我可以成功运行sparkpi示例。
我的集群信息：10.45.10.33（主从，hadoop master，hadoop slave）10.45.10.34（worker，hadoop slave）10.45.10.35（worker，hadoop slave）
但当我尝试运行“spark shell--master yarn”时，它给出了一个例外：

16/09/12 19:50:29 ERROR SparkContext: Error initializing SparkContext.
org.apache.spark.SparkException: Yarn application has already ended! It might have been killed or unable to launch application master.
