--------------------------------------
Summary: 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: 2.2.1, 1.9
Reporter: Sebastian Nagel
Priority: Minor
Fix For: 2.3, 1.10
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.
