Oozie和猪行动：如何在job-xml中包含猪param？

Question

我们可以在job-xml文件中包含一个属性，作为要运行的pig param引用吗？每当我运行代码时，我都会收到“变量无法解析”的错误。

以下是我的代码示例：

猪行动代码：

 <action name="tester-bundle">
        <pig>
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
        <job-xml>${nameNode}/user/cloudera/coordb/job.xml</job-xml>
            <configuration>
                <property>
                    <name>oozie.use.system.libpath</name>
                    <value>true</value>
                </property>
            </configuration>
            <script>/user/cloudera/test-inputs/testa3a.pig</script>
              <param>inputdata=${inputdata}</param>
          <param>outdir=${outpath}</param>
        </pig>
        <ok to="end"/>
        <error to="kill"/>
    </action>

Job.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <property>
        <name>outpath</name>
        <value>hdfs://localhost.localdomain:8020/user/cloudera/test2/20150318</value>
    </property>
</configuration>
