Hi contributors, I’m trying to setup zeppelin v0.9.0 on Kubernetes, however when I try to download jar using “flink.execution.packages”, I got an error like below. But I could connect to maven repo https://repo1.maven.org/maven2/ in zeppelin container and interpreter container.
Could we set the timeout to a larger value? Can you give a hand on how to diagnose / fix this problem? Thx! org.apache.zeppelin.interpreter.InterpreterException: org.apache.zeppelin.interpreter.InterpreterException: org.apache.zeppelin.shaded.org.eclipse.aether.RepositoryException: Cannot fetch
