Nutch 1.16 Release 02/10/2019 (dd/mm/yyyy)
Release Report: https://s.apache.org/l2j94
Comments
- schema.xml has been moved to indexer-solr plugin directory. This file is provided as a
reference/guide for Solr users (NUTCH-2654)
Breaking Changes
- The value of crawl.gen.delay is now read in milliseconds as stated in the description
in nutch-default.xml. Previously, the value has been read in days, see NUTCH-1842 for
further information.
- HostDB entries have been moved from Integer to Long in order to accomodate very large
hosts. Remove your existing HostDB and recreate it with bin/nutch updatehostdb, see
NUTCH-2694 for additional information.
- The signature class TextProfileSignature has been improved to be stable over
consecutive runs by sorting tokens by frequency first and secondarily in lexicographic
order. If an existing CrawlDb contains signatures generated by TextProfileSignature
these are likely to change when upgrading to Nutch 1.16. The previous behavior relying
on a semi-stable pseudo-random hash sorting could be restored setting the property
`db.signature.text_profile.sec_sort_lex` to `false`. See also NUTCH-2381.
Bug
[NUTCH-1063] - OutlinkExtractor test generates an exception but does not fail
[NUTCH-1842] - crawl.gen.delay has a wrong default value in nutch-default.xml or is being parsed incorrectly
[NUTCH-2279] - LinkRank fails when using Hadoop MR output compression
[NUTCH-2381] - In some situations the class TextProfileSignature gives different signatures for the same text "profile" page.
[NUTCH-2387] - Nutch should not index document with "noindex" meta
[NUTCH-2457] - Embedded documents likely not correctly parsed by Tika
[NUTCH-2475] - If and else-if branches has the same condition
[NUTCH-2482] - index-geoip not to add null values to document fields
[NUTCH-2585] - NPE in TrieStringMatcher
[NUTCH-2598] - URLNormalizerChecker fails on invalid URLs in input
[NUTCH-2606] - MIME detection is wrong for plain-text documents send as Content-Type "application/msword"
[NUTCH-2635] - Generator writes unneeded temporary output

Comments
Fellow committers, Nutch 1.12 contains a breaking change NUTCH-2220. Please use the note below and
in the release announcement and keep it on top in this CHANGES.txt for the Nutch 1.12 release.
* replace your old conf/nutch-default.xml with the conf/nutch-default.xml from Nutch 1.12 release
* if you use LinkDB (e.g. invertlinks) and modified parameters db.max.inlinks and/or db.max.anchor.length
