             Summary: New configuration for CommonCrawlDataDumper tool
                 Key: NUTCH-1975
                 URL: https://issues.apache.org/jira/browse/NUTCH-1975
             Project: Nutch
          Issue Type: Improvement
          Components: tool
    Affects Versions: 1.9
            Reporter: Giuseppe Totaro
            Priority: Minor


Hi all, you can find in attachment a new patch including support for new options for {{CommonCrawlDataDumper}}.
In particultar, new options are passed to {{CommonCrawlFormat}} object (which provides methods to create JSON output) using a configuration object ({{CommonCrawlConfig}}).

In particular, in this patch {{CommonCrawlDataDumper}} provides support for the following options:
* {{-SimpleDataFormat}}: enables timestamps in GMT epoche (milliseconds) format.
* {{-epochFilename}}: files extracted will be organized in a reversed-NDS tree based on the FQDN of the webpage, followed by a SHA1 hash of the complete URL. Scraped data will be stored in these directories as individual GMT-timestamped files using "epoche time (in milliseconds)" plus file extension.
* {{-jsonArray}}: organizes both request and response headers into a JSON array instead of using a JSON sub-object.
*{{-reverseKey}}: enables to use the same layout as described for -epochFilename option, with underscore in place of directory separators.

You can use the options above in addition to the options already supported, as described in the [Nutch wiki|https://wiki.apache.org/nutch/CommonCrawlDataDumper] page.
This patch starts from [NUTCH-1974|https://issues.apache.org/jira/browse/NUTCH-1974].

Thanks [~chrismattmann] and [~annieburgess] for supporting me on this work.
