Hi Folks, Spark 2.2.x will be EOL[1] from January of 2019. So I am considering to deprecate support for spark 2.2.x and earlier version in Zeppelin 0.9.0. Deprecation means that from Zeppelin 0.9 user is still able to run spark 2.2.x and earlier version, but will see a warning message in frontend about this deprecation. And in the next major version(maybe 0.10, or 1.0), we would totally remove support for spark 2.2.x and earlier version. The impact for users is the deprecation message in frontend. It may cause issues for users if they use rest api of zeppelin to run paragraph, then fetch and parse the result.
Let me know your concern about this. Thanks [1] https://spark.apache.org/versioning-policy.html -- Best Regards Jeff Zhang
