Subject Split Mapper Output
Date Wed, 12 Oct 2011 19:00:36 GMT
Hi, all,

I am trying to write an application which needs the mapper to split its output to file and
reducer.
For example, if a mapper produces two key-value pairs (a, 1) and (b, 2), how can I write record
(a, 1) directly to a file on HDFS, while still pass record (b, 2) to a reducer?

Best,
Ke
