LinkRank inverter to ignore records without Node
Key: NUTCH-1299
URL: https://issues.apache.org/jira/browse/NUTCH-1299
Project: Nutch
Issue Type: Bug
Affects Versions: 1.4
Reporter: Markus Jelsma
Assignee: Markus Jelsma
Fix For: 1.5
Attachments: NUTCH-1299-1.5-1.patch, NUTCH-1299-1.5-2.patch
No Node object is passed from the inverter's mapper to the reducer, which
expects one, causing the following exception:
{code}
java.lang.NullPointerException

{code}
This never happens unless you have a funky web graph. Our web graph changes
frequently, adding and deleting records. It's likely a large number of
records deleted from the outlink database is responsible for this. This
error, however, only showed up now, a great deal of time after we began
deleting records.
