Hi Jun,
What is the file, list, string [] in this context? I mean to say which file or list or string[]. The new MR (org.apache.hadoop.mapreduce.*) APIs has a parameter “context”. Request you to browse through the APIs of Context (Inherited from JobContext->TaskAttemptContext). The context parameter may provide you the reference you need.
