druid-pwd-provider-extn-sample

This repository contains sample code for writing a Druid extension which shows how to write a "secure" druid "io.druid.metadata.PasswordProvider" that enables you to store/specify your database password in more secure ways than to write them in plain text in the druid configuration file.

General Documentation for writing Druid Extensions is available at -- http://druid.io/docs/latest/Modules.html

Basically, your project should contain an implementation of "io.druid.initialization.DruidModule" which is specified in "META-INF/services/io.druid.initialization.DruidModule"

Here is the most basic project layout for druid extension.
