-## Chart Structure

-Drill Helm charts are organized as a collection of files inside the `drill` directory. As Drill depends on Zookeeper for
-cluster co-ordination, a zookeeper chart is inside the [dependencies'](drill/charts) directory. The Zookeeper chart

-### Templates

-Helm Charts contain `templates` which are used to generate Kubernetes manifest files. These are YAML-formatted resource

 There is a service that can be used, but this one will jump from pod, which isn't very unfriendly. This will be fixed in
 the future. A ingress can be made to the service.

 The size of the Drill cluster (number of Drill Pod replicas / number of drill-bits) can not only be manually scaled up
 or down as shown above, but can also be autoscaled to simplify cluster management. When enabled, with a higher CPU
