-Multiple mappers, different parameter values
Abhinav M Kulkarni 2013-04-02, 16:46
I have a situation wherein I have multiple mappers. I am using
MultipleInputs class to add them.
Now, I need to pass different parameters to different mappers. For e.g.
lets say I have a parameter 'num.iterations' that is set differently for
different mappers. One way to pass parameters to mappers is to set them
in a Configuration object:
Configuration conf = new Configuration();
However using this I can't set the value differently for different
mappers. How do I achieve this?
