Zookeeper java.lang.NoClassDefFoundError: org/eclipse/jetty/server/Connector

Question

I am getting the below error when starting Apache HBase with Zookeeper on my mac. I am using openjdk11.

./start-hbase.sh

*************  WARN  [main] admin.AdminServerFactory: Unable to load jetty, not starting JettyAdminServer

Can anyone help me with what I am missing?

Answer 1

Your classloader is missing the required Jetty jars.

In this case, the class org.eclipse.jetty.server.Connector is contained in the jetty-server-<ver>.jar (in a traditional Jetty installation).

You should edit your question and include how you are starting zookeeper/hbase, as much detail as you can, as that could give people clues on how to help you address this issue.
