Hello,
Let's say that we have two maps outputs which will be sorted before the
reducer will start. Doesn't matter what {a,b0,b1,c} mean, but let's
assume that b0=b1.
Map output1 : a, b0
Map output2: c, b1
In this case we can have 2 different sets of sorted data:
1. {a,b0,b1,c} and
2. {a,b1,b0,c} since b0=b1 .
In my particular problem I want to distingush between b0 and b1.
Basically, they are numbers but I have extra-info on which my comparison
will be made.
Now, the question is: how can I change Hadoop default behaviour in order
to control the sorting algorithm on equal keys ?
Thank you in advance.
Best,
Teodor
