>                 Key: MAPREDUCE-579
>                 URL: https://issues.apache.org/jira/browse/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.
