Patrick Wendell commented on SPARK-1701:
----------------------------------------
I think in the current code "slices" are just a (probably redundant) synonym
for "partitions". We could probably clean it up a bit, for instance in example
code and the programming guide. I think in those cases it's best to just say
"partitions".
The number of partitions and the number of tasks are distinct concepts in
general, but in the cases you listed either applies, and I think that saying
"number of tasks" might be slightly more understandable for users.
> Inconsistent naming: "slice" or "partition"

> Components: Documentation, Spark Core

> Throughout the documentation and code "slice" and "partition" are used
> interchangeably. (Or so it seems to me.) It would avoid some confusion for
> new users to settle on one name. I think "partition" is winning, since that
> is the name of the class representing the concept.
> This should not be much more complicated to do than a search & replace. I can
> take a stab at it, if you agree.
