我得到了一个cloudera虚拟机来学习hadoop。我用java创建了一个基本的wordcount程序，并将其导出到一个jar文件中。我试着运行jar文件，但得到了以下结果：

INFO client.RMProxy: Connecting to ResourceManager at /0.0.0.0:8032
ipc.Client: Retrying connect to server: 0.0.0.0/0.0.0.0:8032. Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)
ipc.Client: Retrying connect to server: 0.0.0.0/0.0.0.0:8032. Already tried 1 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)

...

一直持续到10次。我以前从未使用过hadoop，所以我是个新手，不知道我在用它做什么。感谢您的帮助。
