>                 URL: https://issues.apache.org/jira/browse/NUTCH-2518
>             Project: Nutch
>          Issue Type: Bug
>          Components: crawldb, fetcher, generator, hostdb, linkdb
>    Affects Versions: 1.15
>            Reporter: Sebastian Nagel
>            Priority: Blocker
>             Fix For: 1.15
> The return value of job.waitForCompletion() of the new MapReduce API 
> (NUTCH-2375) must always be checked. If it's not true, the job has been 
> failed or killed. Accordingly, the program
> - should not proceed with further jobs/steps
> - must clean-up temporary data, unlock CrawlDB, etc.
> - exit with non-zero exit value, so that scripts running the crawl workflow 
> can handle the failure
> Cf. NUTCH-2076, NUTCH-2442, [NUTCH-2375 PR 
> #221|https://github.com/apache/nutch/pull/221#issuecomment-332941883].
