NUTCH-1957 using MD5 as part of path and filename to solve filename
collision issue
----
> FileDumper output file name collisions
> --------------------------------------
>
> Key: NUTCH-1957
> URL: https://issues.apache.org/jira/browse/NUTCH-1957
> Project: Nutch
> Issue Type: Bug
> Components: tool
> Affects Versions: 1.10
> Reporter: Renxia Wang
> Priority: Minor
> Labels: dumper, filename, tools
>
> The FileDumper extracts file base name and extension and use
> <basename>.<extension>(e.g. given the url
> https://www.aoncadis.org/contact/Yarrow%20Axford/project.html, the
> <basename>.<extension> will be project.html) as the file name to dump the
> file.
> Code from FileDumper.java:
> String url = key.toString();
> String baseName = FilenameUtils.getBaseName(url);
> String extension = FilenameUtils.getExtension(url);
> ...
> String filename = baseName + "." + extension;
> This introduce file name collision and leads to loss of data when using
> bin/nutch dump.
