> Reporter: Paul Rogers
>
> Drill provides the drillbit.sh script to launch Drill. When Drill is run in
> production environments, or when managed by a tool such as Mesos or YARN,
> customers have many options to customize the launch options. We should
> document this information as below.
> The user can configure Drill launch in one of two ways, depending on version.
> $DRILL_HOME/conf/drill-env.sh allows the user to set environment variables
> that control the Drill launch. See the comment below for the list of these
> variables.
> In Drill 1.7 and later, the administrator can set Drill configuration options
> directly on the launch command line in the form:
> drillbit.sh start -Dvariable=value
> For example, to control the control port:
> drillbit.sh start -Ddrill.exec.http.port=8099
