Description

drill-override.conf content:

drill.exec: {
  cluster-id: "drillbits1",
  zk.connect: "localhost:2181",
   impersonation: {
	enabled: true,
	max_chained_user_hops: 3
  },
  security.user.auth: {
	enabled: false,
	packages += "org.apache.drill.exec.rpc.user.security",
	impl: "pam",
	pam_profiles: [ "sudo", "login" ]
  }
}

Note that authentication is disabled enabled: false.

Drill fails during start up:

apache drill> select * from sys.version;
No current connection

If we remove authentication block from config, Drill starts without errors:

drill.exec: {
  cluster-id: "drillbits1",
  zk.connect: "localhost:2181",
   impersonation: {
	enabled: true,
	max_chained_user_hops: 3
  }
}
