[jira] [Created] (NUTCH-1009) Incorrect path when using readdb

Incorrect path when using readdb
--------------------------------

                 Key: NUTCH-1009
                 URL: https://issues.apache.org/jira/browse/NUTCH-1009
             Project: Nutch
          Issue Type: Bug
    Affects Versions: 1.3
            Reporter: Gabriele Kahlout
            Priority: Minor


I've not looked into the code but the path to the data folder is in a part-00000 directory. This seems to occur for unfetched urls only.

{code}
