    Description

      When running Nutch as a mapreduce job on an existing cluster I get an NullPointerException at org.apache.nutch.fetcher.FetcherOutputFormat.checkOutputSpecs.

      The reason is that the passed in reference to the file system is null.
      The attached patch ignores the parameter 'fs' and creates a new reference to the file system.
