Amareshwari Sriramadasu updated MAPREDUCE-598:
----------------------------------------------
Issue Type: Improvement (was: Bug)
> Streaming: better conrol over input splits
> ------------------------------------------
>
> Key: MAPREDUCE-598
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-598
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: contrib/streaming
> Reporter: arkady borkovsky
>
> In steaming, the map command usually expect to receive it's input
> uninterpreted -- just as it is stored in DFS.
> However, the split (the beginning and the end of the portion of data that
> goes to a single map task) is often important and is not "any line break".
> Often the input consists of multi-line docments -- e.g. in XML.
> There should be a way to specify a pattern that separates logical records.
> Existing "Streaming XML record reader" kind of provides this functionality.
> However, it is accepted that "Streaming XML" is a hack and needs to be
> replaced
