Description

We’ve been having a lively discussion about config options. We might want to summarize the discussion in DRILL-4543. Current text:

At the core of the file hierarchy is drill-default.conf. This file is overridden by one or more drill-module.conf files, which are overridden by the drill-override.conf file that you define.

Possible revision:

At the bottom of the hierarchy are the default files that Drill itself provides. The first is drill-default.conf. This file is overridden by one or more drill-module.conf files provided by Drill’s internal modules. These are overridden by the drill-override.conf file that you define. Finally, you can provide overrides on each Drill-bit using system properties of the form -Dname=value passed on the command line:

./drillbit.sh start -Dname=value
