Subject Re: difference between reducefunction and GroupReduceFunction
Date Fri, 22 May 2015 09:58:02 GMT
Thanks Maximilian.

My use case is similar to the example given in the graph analysis.
In graph analysis, the reduce function used is a normal reduce function.
I executed that with both scenarios and your justification is right. the
normal reduce function have a combiner before sorting unlike the GroupReduce
function. 
my question, how is it effecting the performance as the result is same in
both the situation. 


Thanks and Regards,
Santosh
