Add support for a general serialization mechanism for Map Reduce
----------------------------------------------------------------
Key: HADOOP-1986
URL: https://issues.apache.org/jira/browse/HADOOP-1986
Project: Hadoop
Issue Type: New Feature
Components: mapred
Reporter: Tom White
Fix For: 0.16.0
Currently Map Reduce programs have to use WritableComparable-Writable key-value
pairs. While it's possible to write Writable wrappers for other serialization
frameworks (such as Thrift), this is not very convenient: it would be nicer to
be able to use arbitrary types directly, without explicit wrapping and
unwrapping.
