Subject Migration to 0.20.1 issue
Date Sun, 13 Dec 2009 05:57:51 GMT
  I encountered some weird problem when trying to migrate to HaDoop 0.20.1. 
  I have some old Map/Reduce jobs (with old APIs) that do compile and run on the new cluster.
But they return no result.
  On a closer look, the configuration() and close() functions of the Mapper class are called
during the map phase. But the map() function is not. That's why it outputs 0 record.

Any idea what's going on?
