Marcelo Vanzin commented on SPARK-4492:
---------------------------------------
bq. but every single time I move to a new cluster I spend MORE time working out
how to build it and run it than I do writing the algorithms
Rule of thumb is not to package things that are provided by the cluster. If you
follow that rule, and stick to public, non-developer / non-experimental APIs,
you should have no trouble at all moving to different versions.
