Hi, 1. what's the difference between building pinot-0.12.0 from source code with

-Pbuild-shaded-jar

and without it? 2. Is it possible to shade

org.apache.hadoop

being used in main pom.xml in pinot-0.12.0, seems like it's using different version then hadoop being used in our team's cluster. I believe, if we can shade it and build pinot from source code, then it should be fine.
