Curious if there is there has been any discussion regarding the minimum version of Spark to support in Zeppelin.
For example – it could be “current version plus 2 previous versions”. 1.6.x, 1.5.x, 1.4.x (if Spark ever changes the major version to 2.x.x, it could be latest Major version and previous major + 3 minors, etc.) It seems the number of profiles that need to run in the Travis CI jobs will continue to grow (thus slower tests). It could also reduce the maintenance / regression burden. Does anybody know if Databricks (or chatter on Apache Spark User lists) has stats on % of users on each version? Regards, Jeff
