我通过oozie执行一个java程序，并且就是执行的mahout命令，一直map在这里不动是为什么呢？
下面是我写的java action
<action name="java-node">
<java>
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<prepare>
<delete path="${tempDir}"/>
<delete path="${outputDir}"/>
</prepare>
<configuration>
<property>
<name>mapred.job.queue.name</name>
<value>${queueName}</value>
</property>
</configuration>
