Description

See parent issue. There is a CLASSPATH issue when running against hadoop3 that needs resolving. Meantime, the canary fails to run with a cryptic message (mentioned in the parent in full but it is 'Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.shaded.org.eclipse.jetty.server.HttpConfiguration$Customizer' in short). This will surprise operators who are used to the canary's previous pure-cli experience. Let me make it so you ask for the canary webui; by default, it does not come up.
