Affects Version/s: None
Fix Version/s: 0.20.0
Release Note:Replaced parameters with context obejcts in Mapper, Reducer, Partitioner, InputFormat, and OutputFormat classes.
This is a big change, but it will future-proof our API's. To maintain backwards compatibility, I'd suggest that we move over to a new package name (org.apache.hadoop.mapreduce) and deprecate the old interfaces and package. Basically, it will replace:
public interface Mapper extends JobConfigurable, Closeable
public interface Mapper extends Closable
where MapContext has the methods like getKey(), getValue(), collect(Key, Value), progress(), etc.
