OOzie Shell-Impala操作XML错误

我正在尝试使用ozzie运行一个示例impala查询。运行shell时,我遇到了以下错误

错误:E0701:E0701:XML架构错误,cvc复杂类型。2.3:元素 “shell”不能有字符[children],因为类型的内容

工作流。HDFS中的xml

  <workflow-app name="shell-impala-select-wf" xmlns="uri:oozie:workflow:0.4">
    <start to="shell-impala-select"/>
        <action name="shell-impala-select">
            <shell xmlns="uri:oozie:shell-action:0.1">
                <job-tracker>${jobTracker}</job-tracker>
                <name-node>${nameNode}</name-node>
                <configuration>
                    <property>
                        <name>mapred.job.queue.name</name>
                        <value>${queueName}</value>
                    </property>
                </configuration>
                <exec>script.sh</exec>
                <file>${appPath}/script.sh#script.sh</file>
                <file>${appPath}/first_impala.iql#first_impala.iql</file>
           </shell>
           <ok to="end"/>
           <error to="kill"/>
        </action>
      <kill name="kill">
             <message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
      </kill>
    <end name="end"/>
</workflow-app>

我检查了…这是一个有效的XML.first_impala。iql有一个select-count(*)查询。
