add a record I/O framework to hadoop
------------------------------------

         Key: HADOOP-65
         URL: http://issues.apache.org/jira/browse/HADOOP-65
     Project: Hadoop
        Type: New Feature
  Components: io, ipc  
    Versions: 0.2    
    Reporter: Sameer Paranjpye
    Priority: Minor
     Fix For: 0.2


Hadoop could benefit greatly from a simple record I/O framework that enables the specification of simple record types and enables the generation of code for serialization/deserialization in multiple target languages. The framework would handle a small well understood set of primitive types and simple compositions of these (structs, vectors, maps) . It would be possible to leverage this framework to express I/O in MapReduce computations and to use this as the basis for Hadoops RPC implementation. This would make interfacing with code in languages other than Java much easier.
