> In HIVE-17088{*},{*} we resolved a NPE thrown from HS2 WebUI by introducing
> javax.servlet.jsp-api. It works as expected when the javax.servlet.jsp-api
> jar prevails jetty-runner jar, but things can be different in some
> environments, it still throws NPE when opening the HS2 web:
> {noformat}
> java.lang.NullPointerException
