             Summary: NutchField to support long
                 Key: NUTCH-1675
                 URL: https://issues.apache.org/jira/browse/NUTCH-1675
             Project: Nutch
          Issue Type: Bug
            Reporter: Markus Jelsma
            Assignee: Markus Jelsma


NutchField has no support for Long in readfields. Usually this is not a problem because in reducers it is only written to the output. But when using NutchField in mappers, then a reducer cannot read a Long.
