Oozie使用问题

我使用Oozie向Hadoop2.2发送测试用例Map-Reduce报如下异常，哪位大神帮我解答一下，谢谢。。。

在Hadoop能够成功看到Oozie已成功提交的Job，上面的日志是在Hadoop的子节点中提取的。。。。

红字部分，ip不正确。你看看是什么原因造成的

IP那个应该没啥问题，主要是下面的几个false的问题。。。

你可以排除定位一下错误：看看是你的程序问题，还是Oozie的问题。
你可以先不通过Oozie来提交，你直接提交看看是否会产生这个问题。

还有像发生这种错误，就是没有远程服务器没有响应。
你看看ssh,防火墙，hdfs空间等等排查一下。

很多异常都会有你标识的红字部分，建议看看为什么通信失败。
就是楼上说的，ssh，防火墙之类的，确保都没有问题。

通信都没问题，我在本机发送hadoop任务都能成功执行。。。

ooize提交的任务和普通的map——reduce任务比较，在tmp--->staging->job***文件夹中的内容有不同
oozie提交的结果中没有job.jar,普通map_reduce提交的结果中有job.jar
