--------------------------------------
Summary: Generator: NPE when extracting the host part of a URL
fails
Key: NUTCH-3044
URL: https://issues.apache.org/jira/browse/NUTCH-3044
Project: Nutch
Issue Type: Bug
Components: generator
Affects Versions: 1.20
Reporter: Sebastian Nagel
Fix For: 1.21
When extracting the host part of a URL fails, the Generator job fails because
of a NPE in the SelectorReducer. This issue is reproducible if the CrawlDb
contains an malformed URL, for example, a URL with an unsupported scheme
(smb://).
