Subject Re: Multiple Input Data Processing using MapReduce
Date Fri, 31 Dec 2010 12:47:17 GMT
You can use "map.input.split"(something like that, I can't remember..) param
in Configuration.
this param contains the input file path, you can use it to branch your logic
this param can be found in TextInputFormat.java
