TaggedInputSplit should be public
---------------------------------

                 Key: MAPREDUCE-2226
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2226
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
    Affects Versions: 0.20.1
            Reporter: E. Sammer


Currently it's not possible to get at the original InputSplits when using 
MultipleInputs. This is because TaggedInputSplit (used by DelegatingInputFormat 
used by MultipleInputs) is not public. This means things like the following do 
not work:

{code}
public void map(...) {
  FileSplit fis = (FileSplit)((TaggedInputSplit) 
reporter.getInputSplit()).getInputSplit();
  Path p = fis.getPath();
}
{code}

This prevents users from getting at input split specific data.
