Subject How to write a map() method that needs no input?
Date Fri, 08 May 2009 06:10:58 GMT
Sometimes I would like to just execute a certain method in all nodes.
The method does not need inputs. So, there is no need of any
InputFormat implementation class. So, I would want to just write a
Mapper implementation class with a map() method. But, the problem with
map() method is that it always needs inputs. How do I avoid this?
