Hi
Are you able to run the code after eliminating all the spark code. To find
out if the issue is with Jetty or with Spark itself, it could be also due
to conflicting jetty versions in spark and the one you are trying to use.
You can check the dependency graph in maven and check if there are any
dependency conflicts.
mvn dependency:tree -Dverbose
Thanks
