Subject [jira] Created: (MAPREDUCE-2226) TaggedInputSplit should be public
Date Mon, 20 Dec 2010 07:27:01 GMT
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:

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

This prevents users from getting at input split specific data.
