Description

We get en exception from Spark when using the phoenix-spark connector.

2020-09-11 13:29:28,252 WARN [main] component.AbstractLifeCycle: FAILED org.glassfish.jersey.servlet.ServletContainer-62c42a3@f5c8fa49==org.glassfish.jersey.servlet.ServletContainer,jsp=null,order=-1,inst=true,async=true: javax.servlet.UnavailableException: Servlet class org.glassfish.jersey.servlet.ServletContainer is not a javax.servlet.Servlet
 javax.servlet.UnavailableException: Servlet class org.glassfish.jersey.servlet.ServletContainer is not a javax.servlet.Servlet
 at org.spark_project.jetty.servlet.ServletHolder.checkServletType(ServletHolder.java:505)
 This seems to be caused by a conflict between the servlet implementation of jetty, and jersey.

Shading both Jersey libraries in phoenix-client has solved the problem for us.
