Configure MapR-SASL for Sqoop2

This section describes how to configure Sqoop2 to use MapR-SASL. Starting with the MEP 4.0 release, for secure clusters, MapR-SASL is automatically configured for Sqoop2 and you can skip the steps outlined in this section.

When you configure MapR-SASL for Sqoop2, other components that communicate with Sqoop, such as Hue, must also be configured to use MapR-SASL. Complete the following steps on each node that runs the Sqoop2 server:
  1. Remove the # before the following properties in the Authentication configuration section of the sqoop.properties file.
    In Sqoop 1.99.6, the sqoop.properties file is in the following directory: /opt/mapr/sqoop/sqoop-<version>/server/conf/. In Sqoop 1.99.7, the sqoop.properties file is in the following directory: /opt/mapr/sqoop/sqoop-<version>/conf/.
    #org.apache.sqoop.security.authentication.type=CUSTOM
    #org.apache.sqoop.security.authentication.custom_handler=org.apache.hadoop.security.authentication.server.MultiMechsAuthenticationHandler
  2. Restart Sqoop2 server.
    maprcli node services -name sqoop2 -action restart -nodes <space delimited list of nodes>
Note: To start Sqoop2 client with MapR-SASL, run the following command:
sudo -u mapr /opt/mapr/sqoop/sqoop-<version>/bin/sqoop.sh client --custom
