Enable User Impersonation for Hue

About this task

To enable Hue to submit requests on behalf of any other user, complete the following steps:

Procedure

  1. Verify or configure the following lines to the /opt/mapr/hadoop/hadoop-<version>/etc/hadoop/core-site.xml file for all nodes running ResourceManager: 
    <property>
  <name>hadoop.proxyuser.<default_user>.hosts</name>
  <value>*</value>
</property>
  
<property>
  <name>hadoop.proxyuser.<default_user>.groups</name>
  <value>*</value>
</property>
  2. To enable the Hue file browser to view files in the filesystem, add the following proxy user settings in the configuration block of the httpfs-site.xml: 
    <!-- Hue HttpFS proxy user setting -->
<configuration>
  <property>
    <name>httpfs.proxyuser.<default_user>.hosts</name>
    <value>*</value>
  </property>
  
  <property>
    <name>httpfs.proxyuser.<default_user>.groups</name>
    <value>*</value>
  </property>
</configuration>
  3. Perform any additional Hue configurations and then restart Hue so that the changes will take effect. See Starting the Hue Webserver.
    In most cases, mapr is the <default_user>. The <default_user> you specify must also be the default_user that is configured in the [desktop] section of the hue.ini.
    NOTE
    Based on the ecosystem components that you want to use, addition configuration may be required.
