Hi all, how are you resolving the conflicts of jackson packages? zeppelin/lib/* brings version 2.5.3 while Spark 2.1+ has version 2.6.2. For example this issue <https://stackoverflow.com/questions/44697706/zeppelin-jackson-version-is-too-old-error-when-running-spark-streaming> .
This <https://issues.apache.org/jira/browse/ZEPPELIN-2402> might solve it as well - but there must be a way people are currently doing it? Thanks. Which causes the exception (see full attached).
