Upgrade to Nutch 1.12

["Arora, Madhvi" <ma...@Automationdirect.com>]

Hi,


I wanted to find out how to correct the issue below and will appreciate any help.


 I am trying to upgrade to Nutch 1.12. I am using solr 5.3.1. The reason I am upgrading are:
1: https crawling
2: Boilerplate canola extraction through tika

The only problem so far I am having is an IOException. Please see below. I searched and there is an existing jira issue
NUTCH-2269 <https://issues.apache.org/jira/browse/NUTCH-2269>

[NUTCH-2269] Clean not working after crawl - ASF JIRA<https://issues.apache.org/jira/browse/NUTCH-2269>
issues.apache.org
It seems like the database on Lucene can only be called crawldb. However a couple of bundled version we can find online use linkdb for Lucene as default




I get the same error if I try to clean via the old command:
bin/nutch solrclean crawl-adc/crawldb http://localhost:8983/solr/nutch

But cleaning through linkdb worked as said in the jira issue i.e.
bin/nutch solrclean crawl-adc/linkdb http://localhost:8983/solr/nutch


Just want to know if there is a fix or an alternate way of cleaning and if cleaning via linkdb might be okay or what are the repercussions of cleaning via linkdb.
