Using libpam4j as the PAM Authenticator

The libpam4j module is packaged with Drill. The libpam4j module does not have any external dependencies.

To use libpam4j as the PAM authenticator with Drill, complete the following steps:

  1. Add the following configuration to the drill.exec block in the <DRILL_HOME>/conf/drill-override.conf file:

           drill.exec: {
            cluster-id: "drillbits1",
            zk.connect: "<zk-node-hostname>:2181,<zk-node-hostname>:2181,<zk-node-hostname>:2181",
            impersonation: {
              enabled: true,
              max_chained_user_hops: 3
            security: {
                    auth.mechanisms : ["PLAIN"],
            security.user.auth: {
                    enabled: true,
                    packages += "",
                    impl: "pam4j",
                    pam_profiles: [ "sudo", "login" ]
  2. (Optional) To add or remove different PAM profiles, add or delete the profile names in the pam_profiles array in the configuration.
  3. Restart the Drillbit process on each Drill node, as shown:

           <DRILLINSTALL_HOME>/bin/ restart
