Marko A. Rodriguez commented on TINKERPOP-1027:
-----------------------------------------------

This has the added benefit that {{reduceByKey()}} is no longer needed from 
{{InputRDDFormat}} nor {{InputRDD}}. That is huge as it greatly simplifies the 
implementation of formats and RDDs for users.

> Merge view prior to writing graphRDD to output format/rdd
> ---------------------------------------------------------

> [~dalaro] noted that DSEGraph was not happy with the current {{graphRDD}} 
> model when it comes to writing. To make it happy, the view merge needs to 
> happen prior to {{graphRDD}} output. Thus, move the {{mapReduceRDD}} view 
> merge to before {{graphRDD}} writing.
