Question

It is recommended that to use oozie Unix user for the Oozie server, it needs to expand oozie and Hadoop distributuion. So can anyone tell how to configure the Hadoop cluster with proxy user for the oozie process?

Answer 1

Hey,

The following two properties are required in Hadoop core-site.xml:

 <property>
    <name>hadoop.proxyuser.[OOZIE_SERVER_USER].hosts</name>
    <value>[OOZIE_SERVER_HOSTNAME]</value>
  </property>
  <property>
    <name>hadoop.proxyuser.[OOZIE_SERVER_USER].groups</name>
    <value>[USER_GROUPS_THAT_ALLOW_IMPERSONATION]</value>
  </property>

Replace the capital letter sections with specific values and then restart Hadoop.
