hadoop - Oozie Hive Action处于“准备”状态，作业处于“运行”状态

Question

我的Oozie Hive Action 永远处于运行模式。 oozie.log文件中没有显示错误。

<workflow-app xmlns="uri:oozie:workflow:0.2.5" name="example-wf">
<credentials>
            <credential name='hive_credentials' type='hive'>
                    <property>
                         <name>hive.metastore.uris</name>
                         <value>thrift://localhost:9083</value>
                    </property>
            </credential>
</credentials>
<start to="hive-example"/>
<action name="hive-example" cred="hive_credentials">
    <hive xmlns="uri:oozie:hive-action:0.2">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <job-xml>hive-site.xml</job-xml>
            <configuration>
                <property>
                    <name>oozie.log.hive.level</name>
                    <value>DEBUG</value>
                </property>
                <property>
                    <name>oozie.hive.defaults</name>
                    <value>hive-default.xml</value>
                </property>
            </configuration>     
        <script>script.q</script>
        <file>hive-site.xml</file>
    </hive>
    <ok to="end"/>
    <error to="fail"/>
    </action>
    <kill name="fail">
    <message>Workflow failed, error message[${wf:errorMessage(wf:lastErrorNode())}] 
    </message>
   </kill>
   <end name="end"/>
   </workflow-app>

另外我的job.properties如下所示

nameNode=hdfs://hadoopmaster:54310
jobTracker=localhost:54311
workflowRoot=${nameNode}/user/${user.name}/oozie-workflows
oozie.wf.application.path=hdfs://hadoopmaster:54310/home/hadoopuser/Downloads/oozie
workflows

另外我的工作日志如下

我已经将hive-site.xml放在oozie的工作流目录中，并将工作流目录(包含workflow.xml，hive-site.xml，hive-default.xml)上传到HDFS。作业日志中没有错误。所以我不确定我在哪里犯错。任何帮助是极大的赞赏。

群集设置中有多少个容器？
当您执行工作流程时，一个容器将被oozie占用(它将继续保留该容器直到查询执行)，其余的将被用于执行实际的作业。
