Configure Hue to use Drill on Kerberos-Secured Cluster

You can configure Hue to use Drill on a Kerberos-secured cluster.

Procedure

  1. Configure Hue to use Drill:
    1. In the hue.ini, go to the Drill section, and set the parameters. For example: 
      [librdbms]
  [[databases]]
    ...
    [[[drill]]]

    # Name to show in the UI.
    nice_name=”Drill”

    # Database backend to use.
    engine=drill

    # Connection type. This can be:
    # 1. direct
    # 2. zookeeper
    connection_type=direct

    # Drillbit address for direct connection.
    drillbits=<node>:31010

    # Security mechanism of authentication none/GSSAPI/MAPR-SECURITY.
    mechanism=GSSAPI

    # Available options:
    # "impersonation" to enable or disable outbound impersonation.
    # "principal" of Drill service. Used when Kerberos authentication is enabled.
    options='{"impersonation": true, "principal": "mapr/<node>@REALM"}'
  2. Restart Hue to apply the updated configuration: 
    maprcli node services -name hue -action restart -nodes <node>
