tasks' classpath
----------------------------------------------------------------------------------------------
Key: MAPREDUCE-1938
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1938
Project: Hadoop Map/Reduce
Issue Type: New Feature
Components: job submission, task, tasktracker
Reporter: Devaraj Das
Fix For: 0.22.0
It would be nice to have the ability in MapReduce to allow users to specify for
their jobs alternate implementations of classes that are already defined in the
MapReduce libraries. For example, an alternate implementation for
CombineFileInputFormat.
