> Saving mapping of dumped file to URL
> ------------------------------------
>
> Key: NUTCH-2370
> URL: https://issues.apache.org/jira/browse/NUTCH-2370
> Project: Nutch
> Issue Type: Improvement
> Reporter: Madhav Sharan
> Priority: Minor
>
> - nutch dump [0] is a great tool to simply dump all the crawled files from
> nutch segments.
> - After dump we loose information about URL from which this file was crawled.
> URL is used to name dumped file but that information is encrypted.
> - In `reverseUrlDirs` option one can figure out URL by checking the file path
> but even accessing file path is little complicated than simple mapping file.
> - In `flatdir` there is no way to know actual URL.
> I am submitting a PR which edits [0] and saves a json for each crawled
> segment which maps a file path to URL.
