Description

   Currently, Kylin package xml file for RDBMS, if I want to change the configuration for MySQL datasource like change some function mapping relation, the only way is to change the source code and repackage it.Which is annoying.

   Inspired by kylin.properties.override , I find it easy to solve this problem.

   How to do this:

      1. ${KYLIN_HOME}/conf ,make a new directory named datasource

      2. copy mysql.xml(for example) to ${KYLIN_HOME}/conf/datasource, change its name to mysql.xml.override.Thus you can modify that xml file whatever you want.

      3. Restart Kylin.
