--------------------------------------
Summary: ARG_SEGMENT usage
Key: NUTCH-2441
URL: https://issues.apache.org/jira/browse/NUTCH-2441
Project: Nutch
Issue Type: Improvement
Components: metadata
Affects Versions: 1.13
Reporter: Semyon Semyonov
Fix For: 1.14
The class metadata/Nutch.java public static final String ARG_SEGMENT =
"segment" is not used correctly. In some cases Fetcher and ParseSegment it is
interpreted as a single segmenet, in others CrawlDb, LinkDb, IndexingJob as an
array of segments. Such misunderstanding leads to inconsistency of usage of the
parameter.
After a discussion with [~wastl-nagel] the proposed solution is to allow the
usage of both array and a string in all cases. That gives an opportunity to not
introduce the broken changes.
A path is proposed.
*The question left is refactoring, all these five components share the same
code(two versions of the same code to be precise). Shouldn't we extract a
method and reduce duplicates? *
