>    Affects Versions: 1.9
>            Reporter: Diaa
>            Assignee: Julien Nioche
>            Priority: Minor

> 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.
