Installing Drill on the Cluster

You install Drill on nodes in the cluster, configure a cluster ID, and add Zookeeper information, as described in the following steps:

1. Download the latest version of Apache Drill here or from the Apache Drill mirror site with the command appropriate for your system:
   • wget http://apache.mirrors.hoobly.com/drill/drill-1.18.0/apache-drill-1.18.0.tar.gz
   • curl -o apache-drill-1.18.0.tar.gz http://apache.mirrors.hoobly.com/drill/drill-1.18.0/apache-drill-1.18.0.tar.gz
2. Extract the tarball to the directory of your choice, such as /opt:
   tar -xzvf apache-drill-<version>.tar.gz

3. In drill-override.conf, use the Drill cluster ID, and provide ZooKeeper host names and port numbers to configure a connection to your ZooKeeper quorum.
   a. Edit drill-override.conf located in the conf directory.
   b. Provide a unique cluster-id and the ZooKeeper host names and port numbers in zk.connect. If you install Drill on multiple nodes, assign the same cluster ID to each Drill node so that all Drill nodes share the same ID. The default ZooKeeper port on the open source version of Apache Drill is 2181.

   Example

   drill.exec:{
    cluster-id: "<mydrillcluster>",
    zk.connect: "<zkhostname1>:<port>,<zkhostname2>:<port>,<zkhostname3>:<port>"
   }
