[jira] [Created] (NUTCH-1766) Generator to unlock crawldb and remove tempdir if generate job fails

Diaa created NUTCH-1766:
---------------------------

             Summary: Generator to unlock crawldb and remove tempdir if generate job fails
                 Key: NUTCH-1766
                 URL: https://issues.apache.org/jira/browse/NUTCH-1766
             Project: Nutch
          Issue Type: Bug
          Components: generator
    Affects Versions: 1.9
            Reporter: Diaa
            Priority: Minor
             Fix For: 1.9


Currently if the generate job fails the following happens:
1. generate temp directory remains
2. crawldb remains in lock

The next time generate is called the following happens:
IO exception due to crawldb being in lock mode

Attached is a patch that cleans up after a job fails in generate by unlocking crawldb and removing the generate temp directory so that if a job fails the next time generate is called it wouldn't give an IO Exception.
