Lewis John McGibbney updated NUTCH-2222:
----------------------------------------
Description:
This problem happens at the the second time I crawl a page
{code}
bin/nutch inject urls/
bin/nutch generate -topN 1000
bin/nutch fetch -all
bin/nutch parse -force -all
bin/nutch updatedb -all
{code}
seconde time (re-fetch) :
{code}
bin/nutch generate -topN 1000 --> batchid changes for all existing pages
bin/nutch fetch -all --> *** metadatas are delete for all pages already
crawled **
bin/nutch parse -force -all
bin/nutch updatedb -all
{code}
I reproduce it with mongodb 2.6, mongodb 3.0, and hbase-0.98.8-hadoop2
It happens only if the page has not changed
To reproduce easily, please add to nutch-site.xml :
{code}
<property>
<name>db.fetch.interval.default</name>
<value>60</value>
<description>The default number of seconds between re-fetches of a page (1
minute)

{code}
