> bin/crawl: use function to run bin/nutch and check exit value
> -------------------------------------------------------------
>
> Key: NUTCH-1883
> URL: https://issues.apache.org/jira/browse/NUTCH-1883
> Project: Nutch
> Issue Type: Improvement
> Affects Versions: 1.9, 2.2.1
> Reporter: Sebastian Nagel
> Assignee: Sebastian Nagel
> Priority: Minor
> Fix For: 2.3, 1.10
>
> Attachments: NUTCH-1883-2x-v1.patch, NUTCH-1883-trunk-v1.patch,
> NUTCH-1883-trunk-v2.patch, NUTCH-1883-trunk-v2.patch

>
> In bin/crawl for every Nutch command the exit value is checked explicitly:
> {code}
> "$bin/nutch" ...
> RETCODE=$?
> if [ $RETCODE -ne 0 ]
> then exit $RETCODE
> fi
> {code}
> This could be simplified by calling bin/nutch from one function which does
> the check. The function could also echo the command, show an error message,
> etc. The main advantage is short and clear code. In case a special treatment
> of exit values is required (cf. NUTCH-1829) we still could call bin/nutch
> directly.
