Subject Setting number of mappers according to number of TextInput lines
Date Sat, 16 Jun 2012 09:01:26 GMT
Hello,

I have very small input size (kB), but processing to produce some output 
takes several minutes. Is there a way how to say, file has 100 lines, i 
need 10 mappers, where each mapper node has to process 10 lines of input 
file?

Thanks for advice.
