Modifying the core-site.xml File

In the core-site.xml file, provide the shortname for the Kerberos principal as shown. In addition, verify that you configured the proxyuser during configuration. See Configuring Hue 3.x (MapR 4.0.x space) for details.

<!-- Hue security configuration -->
<property>
  <name>hue.kerberos.principal.shortname</name>
  <value>mapr</value>

<property>
  <name>hadoop.proxyuser.mapr.groups</name>
