Hi, I was wondering why Zeppelin does not have `org.apache.hadoop:hadoop-common:\{version}` when installing Zeppelin server.

I know that the file is not necessary for all the cases, but for JDBC kerberos it is needed.

I notice that the scope is "provided" in pom.xml file which means that I need to add it myself.

Well if it is not necessary jar file, then how about adding comments to official document that in order to use `zeppelin.jdbc.auth.type` as `KERBEROS` you need to add custom dependency that matches your hadoop version (2 or 3)
