[jira] [Created] (NUTCH-1722) FetcherJob#fetch throws NullPointerException for null batchId

Gerhard Gossen created NUTCH-1722:
-------------------------------------

             Summary: FetcherJob#fetch throws NullPointerException for null batchId
                 Key: NUTCH-1722
                 URL: https://issues.apache.org/jira/browse/NUTCH-1722
             Project: Nutch
          Issue Type: Bug
          Components: fetcher
    Affects Versions: 2.2.1
            Reporter: Gerhard Gossen
         Attachments: NUTCH-1722-2.x.patch

The documentation of FetcherJob#fetch claims that a null batchId parameter is interpreted as "fetch all generated fetchlists". However, the implementation tries to do {{batchId.equals(Nutch.ALL_BATCH_ID_STR)}}, which throws a NullPointerException when batchId is null.

The provided patch sets a null batchId to {{Nutch.ALL_BATCH_ID_STR}}, which should be the documented behavior.
