Nandor Kollar commented on PIG-5246:
------------------------------------

[~kellyzly] one comment: Rohini suggested that instead of {{sparkversion=21}} and {{sparkversion=16}} we should use {{sparkversion=2}} and {{sparkversion=1}}. On [RB|https://reviews.apache.org/r/59530/] you can see that the latest patch is modified accordingly.
