Resolution: Duplicate
Duplicate of MAPREDUCE-1785
> Streaming should allow TextInputFormat keys to be passed through
> ----------------------------------------------------------------
>
> Key: MAPREDUCE-1350
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1350
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: contrib/streaming
> Affects Versions: 0.22.0
> Reporter: Todd Lipcon
>
> Streaming's PipeMapper automatically ignores the key (LongWritable file
> offset) coming from TextInputFormat. This is usually what the user wants, but
> occasionally the file offsets are useful - for example, after grepping a
> large file for a particular pattern, you may want to look at the offset in
> the file where the pattern matched. There should be a boolean configuration
> variable which overrides ignoreKey in PipeMapper.java:86
