> it looks like there are some commons-configuration issues that will need
to be worked out for GlobalPhoenixMetricsTestSink.java
Just needs to be switched to the `org.apache.commons.configuration2`
package. Also, GlobalPhoenixMetricsTestSink has a lot of unused imports. Would
be good to make a pass over your changes for those.---
