| This directory contains source code artifacts to launch Drill in cluster mode |
| along with a ZooKeeper. The Drill image is based on a minor customisation of |
| the official Drill image that switches it from an embedded to a cluster mode |
| launch. Logging is redirected to stdout. |
| |
| In the docker-cluster-mode directory: |
| |
| 1. docker build -t apache/drill-cluster-mode |
| 2. docker-compose up |
| |
| Then access the web UI at http://localhost:8047 or connect a JDBC client to |
| jdbc:drill:drillbit=localhost or jdbc:drill:zk=localhost but note that you |
| will need to make the drillbit container hostnames resolvable from the host |
| to use a ZooKeeper JDBC URL. |
| |
| To launch a cluster of 3 Drillbits |
| |
| 3. docker-compose up --scale drillbit=3 |
| |
| but first note that to use docker-compose's "scale" feature to run multiple |
| Drillbit containers on a single host you will need to remove the host port |
| mappings from the compose file to prevent collisions (see the comments |
| on the relevant lines in that file). Once the Drillbits are launched run |
| `docker-compose ps` to list the ephemeral ports that have been allocated on |
| the host. |
