> Key: MAPREDUCE-579

> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: contrib/streaming

>
> The documentation for the Streaming module do not include any mention of the
> "slowmatch" parameter, which checks for CDATA sections while looking for XML
> records.
> An important point is that "slowmatch=true" violates the principle of least
> surprise: the "begin" and "end" parameters become regular expressions instead
> of exact strings. This is probably a useful feature, but should definitely
> be noted since users will be tempted to use the XML record reader on
> not-strictly-xml files, which may require escaping the "begin" and "end"
> patterns.
