Oozieworkflow.xml错误

Question

I am really new to the hadoop eco system and I have been trying to co ordinate and execute a basic pig job via Oozie.

I get the following error when I try to validate my workflow.xml file.

Error:

Invalid app definition, org.xml.sax.SAXParseException; lineNumber: 32; columnNumber: 16; cvc-complex-type.2.3: Element 'workflow-app' cannot have character [children], because the type's content type is element-only.

Here is my workflow.xml file for your reference.

  1 <workflow-app xmlns="uri:oozie:workflow:0.2" name="log-wf">
  2 <start to="pig-node"/>
  3  
  4 <action name="pig-node">
  5     <pig>
  6         <job-tracker>${jobTracker}</job-tracker>
  7         <name-node>${namenode}</name-node>
  8         <prepare>
  9             <delete path="${nameNode}/user/${appRoot}/pigOutput"/>
 10         </prepare>
 11         <configuration>
 12             <property>
 13                 <name>mapred.job.queue.name</name>
 14                 <value>${queueName}</value>
 15             </property>
 16             <property>
 17                 <name>mapred.compress.map.output</name>
 18                 <value>true</value>
 19             </property>
 20         </configuration>
 21         <script>script.pig</script>
 22         <param>piginput=/user/${appRoot}/clean.log</param>
 23         <param>pigoutput=/user/${appRoot}/pigOutput</param>
 24     </pig>
 25     <ok to="end"/>
 26     <error to="fail"/>
 27 </action>
 28 
 29 
 30 
 31  <end name="end"/>
 32 </workflow-app>

I do not understand which element inside the workflow tag is causing the error since there is no 16th column on the 32nd line. Do you guys have any suggestions on this?

It is common to xml files but it's not formatting by itself, just some symbols that are not parsed as whitespace. Review the original workflow file to see what's wrong with it. But in general you can keep your xml files formatted, it's just a matter of having a decent editor :) . – @patrungel

Thanks for your response.
