Which command lines are you using? This works for me (in a non-distributed
environment), where the old index is in crawl/indexes and the one just
created is in crawl/indexes_new :
errexit() {
echo "## $(date): *** LAST COMMAND RETURNED NONZERO STATUS: $? ***"
exit 1
}
[...]
echo "## $(date): Starting to merge new indexes into old..."
MERGE_DATE=$(date +%Y%m%d%H%M)
bin/nutch merge crawl/indexes_merged/${MERGE_DATE} \
crawl/indexes crawl/indexes_new || errexit
# in nutch-site, hadoop.tmp.dir points to crawl/tmp
rm -rf crawl/tmp/*
# create the index.done flag
touch crawl/indexes_merged/${MERGE_DATE}/index.done
# delete indexes_new and replace indexes with indexes_merged
rm -rf crawl/indexes_new
mv crawl/indexes crawl/indexes_old
mv crawl/indexes_merged crawl/indexes
rm -rf crawl/indexes_old
echo "## $(date): Re-indexing completed, making webapp aware of that..."
touch -c /usr/share/tomcat5/webapps/nutch*/WEB-INF/web.xml
