Subject Re: Is mango a full replacement of the original map/reduce API?
Date Sat, 27 Feb 2016 13:40:52 GMT

Mango is not a replacement of M/R, but a DSL that works on top of M/R
hiding the implementation details from you. Due to a limited nature,
it cannot be a complete replacement of JS and else M/R function, only
for a subset of simple and trivial ones.
