Hi,
I'm getting the following error:
$ bin/nutch readdb crawl-chat/crawldb -stats
CrawlDb statistics start: crawl-chat/crawldb
Statistics for CrawlDb: crawl-chat/crawldb
Exception in thread "main" java.lang.NullPointerException

The db has been created as follows, as you see no URLs have been
fetched (another problem):
$ bin/nutch crawl urls/chat -dir crawl-chat -depth 10 -topN 10000
solrUrl is not set, indexing will be skipped...
crawl started in: crawl-chat
rootUrlDir = urls/chat
threads = 10
depth = 10
solrUrl=null
topN = 10000
