各位大神，请教一下，我通过oozie，在hadoop中执行shell脚本，oozie控制台打印下面的错误：

Oozie Launcher starts

Oozie Launcher failed, finishing Hadoop job gracefully


Oozie Launcher, uploading action data to HDFS sequence file: hdfs://Master:9000/user/hadoop/oozie-hado/0000000-150430155539137-oozie-hado-W/shell-node--shell/action-data.seq


Oozie Launcher ends


在oozie的web控制台上看到的是failed：


error message：JA017: Unknown hadoop job [job_local1945068546_0001] associated with action [0000000-150430155539137-oozie-hado-W@shell-node]. Failing this action!


查看hdfs上的/user/hadoop/oozie-hado/0000000-150430155539137-oozie-hado-W/shell-node--shell目录，只有这三个文件，没有action.xml：
[root@Master oozie]# hdfs dfs -ls /user/hadoop/oozie-hado/0000000-150430155539137-oozie-hado-W/shell-node--shell

请教一下，action.xml这个文件是从哪来的？怎么会报这个错误？谢谢！

action.xml文件应该是oozie-server向Hadoop提交作业过程中自己生成的，可以讲oozie的debug打开，看看oozie后台日志。再不行，只能跟踪oozie源码了。

这个文件是属于hadoop，你那个进程是不是hadoop的，如果不是得话，即使文件有也找不到~
