Subject Quick one on evaluation
Date Wed, 02 Aug 2017 12:16:44 GMT
Hi Sparkians,

I understand the lazy evaluation mechanism with transformations and actions. My question is
simpler: 1) are show() and/or printSchema() actions? I would assume so...

and optional question: 2) is there a way to know if there are transformations "pending"?

Thanks!

jg
