我在自定义MapR沙箱中运行Oozie。以下是我的job.properties文件信息：
nameNode=maprfs:///
jobTracker=maprfs:///
queueName=default
examplesRoot=examples
oozie.wf.application.path=/user/user01/lab2/exercise4/zayd_hammoudeh_lab2_exercise4/workflow.xml
供参考，以下是我的workflow.xml文件：
<action name="stdev-calc">
<map-reduce>
<job-tracker>${jobTracker}</job-tracker>
<name-node>"${nameNode}"</name-node>
<prepare>
<delete path="/user/user01/lab2/exercise4/OUT"/>
</prepare>
<configuration>
<property>
<name>mapred.mapper.class</name>
<value>Stdev.StdevMapper</value>
</property>
<property>

<value>Stdev.StdevReducer</value>
</property>

</property>
<property>

<value>/user/user01/lab2/exercise4/OUT</value>
</property>
</configuration>
</map-reduce>
<ok to="end"/>
<error to="fail"/>
</action>
<kill name="fail">
<message>Exercise 4 failed with error message: [${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<end name="end"/>
当我尝试完成工作时，我在工作信息中得到以下信息：

我尽我所能找出问题的根源，但没有成功。对于namenode和jobtracker使用“maprfs：///”建议与mapr-oozie包捆绑在一起的示例。任何帮助都会非常感激。
答案 0 :(得分：1)
我之前错过的问题是，当我在名称节点上收到错误时，由于＆＃34; job.properties＆＃34;的内容，它不。文件。相反，它来自＆＃34; workflow.xml＆＃34;文件。我写错了：
<name-node>"${nameNode}"</name-node>
Oozie不会处理引号，如果删除它们，问题就会消失。最后的关键教训是，当您看到不容易解释的Oozie错误时，要小心检查workflow.xml和job.properties文件。
