E0901 Namenode localhost 8020 not allowed not in Oozies whitelist

Question

I am trying to run the example of Oozie, but it is giving me this error. can someone suggest how can I dismiss this?

Answer 1

Hi,

Most probably you need to add some properties in core-site.xml file to solve your whitelist error:

  <property> 
  <name>hadoop.proxyuser.oozie.hosts</name> 
  <value>*</value> 
  </property> 

  <property> 
  <name>hadoop.proxyuser.oozie.groups</name> 
  <value>*</value> 
  </property>

Answer 2

You can add this below property in oozie-site.xml:

<property>
<name>oozie.service.HadoopAccessorService.jobTracker.whitelist</name>
<value>myaddress:8020</value>
</property>

Hope it helps.
