I've setup Apace drill 1.10.0 on RHEL 6.7, HDP 2.5.3, kerberos enabled.

I'm getting below error while running "drill-conf" as user "drill" which is configured in the "drill-override.conf" file and it has valid keytab/ticket.

drill@host:/opt/drill/bin>  drill-conf

Here is my "drill-override.conf" file:

drill.exec: {
  cluster-id: "drillbits1",
  zk.connect: "host1:2181,host2:2181,host3:2181",
  security: {
          user.auth.enabled: true,
          user.auth.impl: "pam",
          user.auth.pam_profiles: [ "sudo", "login" ],
          packages += "org.apache.drill.exec.rpc.user.security",
          auth.mechanisms: ["KERBEROS","PLAIN"],
          auth.principal: "drill/labhdp@LAB.COM",
          auth.keytab: "/opt/drill/.keytab/drill.keytab"
        }
}

Please help me resolve the issue.

Apache has good documentation for this, you need to make sure you have correct kerberos versions.
