我workflow.xml看起来像这样，

`<workflow-app xmlns="uri:oozie:workflow:0.2" name="sample-wf"> 
<start to="java-node"/> 
<action name="java-node"> 
     <java> 
      <job-tracker>${jobTracker}</job-tracker> 
      <name-node>${nameNode}</name-node> 
      <configuration> 
       <property> 
        <name>mapred.job.queue.name</name> 
        <value>${queueName}</value> 
       </property> 
      </configuration> 
      <main-class>com.sample.util.HBaseBulkLoad</main-class> 
       <arg>TEST</arg> 
       <arg>hdfs://centOS/user/sample/input/sample5.txt</arg> 
       <arg>hdfs://centOS/user/sample/HFile</arg> 
     </java> 
     <ok to="end"/> 
     <error to="fail"/> 
    </action> 
    <kill name="fail"> 
     <message>Java failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message> 
    </kill> 
    <end name="end"/> 
</workflow-app>`

我能够使用运行jar文件hadoop jar command但不使用oozie。我在java中设置了所有必需的配置。但仍然得到例外。

HMaster and HRegionServer正在运行。任何人都知道，请帮助我...

确保Oozie作业正在运行的框可以访问您的Zookeeper服务器，否则HBaseClient将无法发现您的HRegionServers。
