> We are using Solr with Nutch to provide a complete search engine for our website.
> I created a cron job that would use Nutch to crawl and update the Solr index each night. This cron job is trying to automatically correct some errors that could result in a corrupt crawldb. However, it seems that the bin/crawl command doesn't correctly propagate errors coming from bin/nutch.
> Here is an exemple from the bin/crawl script :
> $bin/nutch inject $CRAWL_PATH/crawldb $SEEDDIR
> if [ $? -ne 0 ]
> then exit $?
> fi
> Even if there is an error in the nutch inject command, the crawl script always returns 0. The way I understand it, the exit code returned is the result of the shell test and not the result of the nutch inject command.
> To correct this, we would need to modify the script with something like :
> $bin/nutch inject $CRAWL_PATH/crawldb $SEEDDIR
> RETCODE=$?
> if [ $RETCODE -ne 0 ]
> then exit $RETCODE
> fi
