Step 2: Modify drill-override.conf

About this task

For secure and insecure clusters, modify <DRILL_HOME>/conf/drill-override.conf on each Drill node to enable impersonation in Drill, and set the maximum number of chained user hops that Drill allows.

Add the following configuration properties to the drill.exe block in drill-override.conf:

drill.exec: {
 cluster-id: "<drill_cluster_name>",
 zk.connect: "<hostname>:5181,<hostname>:5181,<hostname>:5181"
 impersonation: {
       enabled: true,
       max_chained_user_hops: 3
 }
}
