--------------------------------------
Summary: Reduce size of Nutch job file and package
Key: NUTCH-2608
URL: https://issues.apache.org/jira/browse/NUTCH-2608
Project: Nutch
Issue Type: Improvement
Components: deployment
Affects Versions: 1.15
Reporter: Sebastian Nagel
The Nutch 1.15 binary package and the Nutch job file will reach or even exceed
300 MB. A huge job file isn't ideal as it needs to be distributed in the Hadoop
cluster. There are several reasons for this:
- missing exclusion of unneeded indirect dependencies, e.g.:
-* indexer-elastic includes many Lucene libraries related to query processing
- huge plugins. That can be hardly avoided as these plugins provide also "huge"
functionality, e.g., parse-tika is able to pass a long list of document
formats. However, it should be possible to avoid overlaps between plugins (in
case dependency upgrades can be made at the same time). Hot candidates are:
-* any23 includes tika-parsers as does parse-tika
-* lib-selenium and lib-htmlunit both use selenium and phantomjsdriver libs
Of course, users can easily build smaller packages by excluding unused plugins
in {{src/plugin/build.xml}}. But would be good, at least, to try to reduce the
size of the Nutch package.
