Installing Drill
This topic provides instructions for using package managers to download and install Drill.
Data Fabric Default Security Configuration
Installing Drill Under Warden or YARN
You can install and run Drill under Warden or you can install and run Drill under YARN. If you are currently running Drill under Warden, you can upgrade Drill and continue to run Drill under Warden, or you can migrate Drill to run under YARN. See Migrate Drill to Run Under YARN for instructions.
When Warden manages the Drill cluster, you can use the Control System for monitoring. YARN (Yet Another Resource Negotiator) is a cluster management tool that automates the resource sharing process in a cluster. When you launch Drill under YARN, YARN deploys (localizes) Drill onto each node. You can monitor the Drill cluster using the Drill-on-YARN Application Master web UI.
Drill Packages
You can use package managers to manually install the appropriate Drill package. The Drill
packages provide the software needed to run Drill. Data Fabric provides mapr-drill
package and also a mapr-drill-yarn
package.
Drill includes the Drill daemon, the core Drillbit service that runs on a node. Each node running the Drillbit service can receive, plan, and execute queries sent from a client. The software also includes the drill-shell command line interface, a pure-Java console-based utility, for connecting to a Drill cluster and executing SQL commands.
The following sections list the Drill packages and their descriptions:
- mapr-drill
- The
mapr-drill
package is required to run Drill under the Warden service. This package installs or upgrades the Drill software in/opt/mapr/drill
and integrates Drill with the Warden service. You install this package on all nodes designated to run Drill.NOTEVerify that you get both the mapr-drill and mapr-drill-internal packages, especially if you install or upgrade through the URL or download through the HPE repositories. Also, verify that the packages have the same version. For example, if you install Drill 1.14, both packages should be version 1.14. - mapr-drill-yarn
- The
mapr-drill-yarn
package is required to run Drill under YARN. This package installs the Drill software in/opt/mapr/drill
. You install this package on the node that you designate as the Drill-on-YARN client. See Install Drill to Run Under YARN for details. YARN deploys Drill to every node included in the Drill cluster. Installing this package on every node is not required.
Drill and Query Services
To use the optional OJAI Distributed Query Service, you must install Drill and configure and register the service. See Configure the OJAI Distributed Query Service.
Drill Installation Security Scenarios
The following sections describe some manual installation scenarios for Drill with information about security configuration:
Installing or Upgrading Drill
You can install Drill on a Data Fabric cluster with or without default security. After you install the Drill package, you must run the configuration script, configure.sh -R, to configure the Drill service on the nodes. When you run the configuration script, the script recognizes whether your Data Fabric cluster is using the default security or not, and configures Drill accordingly.
drill-distrib.conf
and distrib-env.sh
files. See Securing
Drill.drill-override.conf
file, but doing so is not recommended or
supported.If your cluster is not using the default security, the internal Drill configuration script does not configure any security for Drill. Instead, it copies warden.drill-bits.conf to the conf.d directory.
Installing Drill with Data Fabric and Configuring Custom Security
- Run
/usr/bin/touch /opt/mapr/conf/.customSecure
to add the .customSecure file. - Run
configure.sh -R
.
The configuration script recognizes the .customSecure file which indicates not to configure the default security settings. At this point, you can manually configure security in drill-override.conf.
