我在hadoop2.4.1三节点集群上运行了spark1.1.1。我打字的时候 ./spark-shell --master yarn-client ，我反复收到以下消息，此消息仍在继续：

15/01/09 09:48:48 INFO cluster.YarnClientSchedulerBackend: Application report from ASM:
         appMasterRpcPort: -1
         appStartTime: 1420796814009
         yarnAppState: ACCEPTED

15/01/09 09:48:49 INFO cluster.YarnClientSchedulerBackend: Application report from ASM:

         appMasterRpcPort: -1
         appStartTime: 1420796814009
         yarnAppState: ACCEPTED

有人请帮忙。我试过到处找，但没有结果。这是显示的完整消息：
