I'm running Apache Zeppelin 0.8.0 in Amazon EMR. Recently the spark interpreter started to fail to pull down library dependencies. This was because the zeppelin.interpreter.dep.mvnRepo configuration parameter was set to http://repo1.maven.org/maven2/ and the maven repo has recently stopped supporting http as outlined here: https://support.sonatype.com/hc/en-us/articles/360041287334
As per the maven documentation I updated the value of this parameter to https://repo1.maven.org/maven2/ but this didn't resolve the issue. Instead updating the value to http://insecure.repo1.maven.org/maven2/ fixed the problem.
It seems like Zeppelin is not working with https for the maven repo. Can anyone confirm if this is the case or is some extra set up required to get this working?
