Need Sample map reduce program

[Nagarajan, Senthil Kumaran (GE, Corporate, consultant)]

Hi.

 

 

I am new to Hadoop Map-reduce programming. Can anyone provide me the
sample map-reduce code for some basic arithmatic calculations. Like,
read the data from from the text /csv files and then do some
addition/sub/multi/div operations and produce the output.

 

Kindly anyone help me on this.

 

Thanks

Senthil
