8 November 2016 - Apache Solr™ 6.3.0 Available

The Lucene PMC is pleased to announce the release of Apache Solr 6.3.0.

Solr is the popular, blazing fast, open source NoSQL search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search and analytics, rich document parsing, geospatial search, extensive REST APIs as well as parallel SQL. Solr is enterprise grade, secure and highly scalable, providing fault tolerant distributed search and indexing, and powers the search and navigation features of many of the world's largest internet sites.

Solr 6.3.0 is available for immediate download at: http://lucene.apache.org/solr/mirrors-solr-latest-redir.html

Highlights of this Solr release include:

DocValues, streaming, /export, machine learning

  • Optimize, store and deploy AI models in Solr

  • Ability to add custom streaming expressions

  • New streaming expressions such as "fetch", "executor", and "commit" added.

  • Parallel SQL accepts <, >, =, etc., symbols.

  • Support facet scoring with the scoreNodes expression

  • Retrieving docValues as stored values was sped up by using the proper leaf reader rather than ask for a global view. In extreme cases, this leads to a 100x speedup.

Faceting:

  • facet.method=enum can bypass exact counts calculation with facet.exists=true, it just returns 1 for terms which exists in result docset

  • Add "overrequest" parameter to JSON Facet API to control amount of overrequest on a distributed terms facet

Logging:

  • You can now set Solr's log level through environment variable SOLR_LOG_LEVEL

  • GC logs are rotated by JVM to a max of 9 files, and backed up via bin/solr scripts

  • Solr's logging verbosity at the INFO level has been greatly reduced by moving much logging to DEBUG level

  • The solr-8983-console.log file now only logs STDOUT and STDERR output, not all log4j logs as before

  • Solr's main log file, solr.log, is now written to SOLR_LOGS_DIR without changing log4j.properties

Start scripts:

  • Allow 180 seconds for shutdown before killing solr (configurable, old limit 5s) (Unix only)

  • Start scripts now exits with informative message if using wrong Java version

  • Fixed "bin/solr.cmd zk upconfig" command which was broken on windows

  • You can now ask for DEBUG logging simply with '-v' option, and for WARN logging with '-q' option

SolrCloud:

  • The DELETEREPLICA API can accept a 'count' parameter and remove "count" number of replicas from each shard if the shard name is not provided

  • The config API shows expanded useParams for request handlers inline

  • Ability to create/delete/list snapshots at collection level

  • The modify collection API now waits for the modified properties to show up in the cluster state before returning

  • Many bug fixes related to SolrCloud recovery for data safety and faster recovery times.

Security:

  • SolrJ now supports Kerberos delegation tokens

  • Pooled SSL connections were not being re-used. This is now fixed.

  • Fix for the blockUnknown property which made inter-node communication impossible

  • Support SOLR_AUTHENTICATION_OPTS and SOLR_AUTHENTICATION_CLIENT_CONFIGURER in windows bin/solr.cmd script

  • New parameter -u in bin/post to pass basicauth credentials

Misc changes:

  • Optimizations to lower memory allocations when indexing JSON as well as for replication between solr cloud nodes.

  • A new Excel workbook (.xlsx) response writer has been added. Use 'wt=xlsx' request parameter on a query request to enable.

8 February 2016 - Apache Lucene/Solr development moves to GIT

As of January 23rd 2016, Lucene/Solr source code is hosted in Apache's GIT repository. This means that the old SVN repository is now stale and should not be used. For information on working with git, please consult the Solr web site and the wiki.

The GitHub mirror remains at the same location as before, but the contents have changed. We now have one unified repo preserving the full history of both Lucene and Solr. If you had a GitHub fork, you will find that it has changed its "forked from" location, and any Pull Request will go to that other fork instead of to the Lucene developers. The only known solution is to delete your existing fork and re-fork from GitHub.

If you had active code changes and Pull Requests against our old GitHub mirror, please see the wiki for some suggestions on how to proceed.

The PMC is happy to answer any question you may have regarding this change.

18 August 2014 - Recommendation to update Apache POI in Apache Solr 4.8.0, 4.8.1, and 4.9.0 installations

Apache Solr versions 4.8.0, 4.8.1, 4.9.0 bundle Apache POI 3.10-beta2 with its binary release tarball. This version (and all previous ones) of Apache POI are vulnerable to the following issues:

CVE-2014-3529: XML External Entity (XXE) problem in Apache POI's OpenXML parser

Information disclosure: Apache POI uses Java's XML components to parse OpenXML files produced by Microsoft Office products (DOCX, XLSX, PPTX,...). Applications that accept such files from end-users are vulnerable to XML External Entity (XXE) attacks, which allows remote attackers to bypass security restrictions and read arbitrary files via a crafted OpenXML document that provides an XML external entity declaration in conjunction with an entity reference.

CVE-2014-3574: XML Entity Expansion (XEE) problem in Apache POI's OpenXML parser

Denial of service: Apache POI uses Java's XML components and Apache Xmlbeans to parse OpenXML files produced by Microsoft Office products (DOCX, XLSX, PPTX,...). Applications that accept such files from end-users are vulnerable to XML Entity Expansion (XEE) attacks ("XML bombs"), which allows remote hackers to consume large amounts of CPU resources.

The Apache POI PMC released a bugfix version (3.10.1) today.

Solr users are affected by these issues, if they enable the "Apache Solr Content Extraction Library (Solr Cell)" contrib module from the folder "contrib/extraction" of the release tarball.

Users of Apache Solr are strongly advised to keep the module disabled if they don't use it. Alternatively, users of Apache Solr 4.8.0, 4.8.1, or 4.9.0 can update the affected libraries by replacing the vulnerable JAR files in the distribution folder. Users of previous versions have to update their Solr release first, patching older versions is impossible.

To replace the vulnerable JAR files follow these steps:

  • Download the Apache POI 3.10.1 binary release.

  • Unzip the archive.

  • Delete the following files in your "solr-4.X.X/contrib/extraction/lib" folder:

    • poi-3.10-beta2.jar
    • poi-ooxml-3.10-beta2.jar
    • poi-ooxml-schemas-3.10-beta2.jar
    • poi-scratchpad-3.10-beta2.jar
    • xmlbeans-2.3.0.jar
  • Copy the following files from the base folder of the Apache POI distribution to the "solr-4.X.X/contrib/extraction/lib" folder:

    • poi-3.10.1-20140818.jar
    • poi-ooxml-3.10.1-20140818.jar
    • poi-ooxml-schemas-3.10.1-20140818.jar
    • poi-scratchpad-3.10.1-20140818.jar
  • Copy "xmlbeans-2.6.0.jar" from POI's "ooxml-lib/" folder to the "solr-4.X.X/contrib/extraction/lib" folder.

  • Verify that the "solr-4.X.X/contrib/extraction/lib" no longer contains any files with version number "3.10-beta2".

  • Verify that the folder contains one xmlbeans JAR file with version 2.6.0.

If you just want to disable extraction of Microsoft Office documents, delete the files above and don't replace them. "Solr Cell" will automatically detect this and disable Microsoft Office document extraction.

Coming versions of Apache Solr will have the updated libraries bundled.

12 March 2014 - Apache Solr 4.8 will require Java 7

The Apache Solr committers decided with a large majority on the vote to require Java 7 for the next minor release of Apache Solr (version 4.8)!

The next release will also contain some improvements for Java 7:

  • Better file handling (especially on Windows) in the directory implementations. Files can now be deleted on windows, although the index is still open - like it was always possible on Unix environments (delete on last close semantics).

  • Speed improvements in sorting comparators: Sorting now uses Java 7's own comparators for integer and long sorts, which are highly optimized by the Hotspot VM.

If you want to stay up-to-date with Lucene and Solr, you should upgrade your infrastructure to Java 7. Please be aware that you must use at least use Java 7u1. The recommended version at the moment is Java 7u25. Later versions like 7u40, 7u45,... have a bug causing index corrumption. Ideally use the Java 7u60 prerelease, which has fixed this bug. Once 7u60 is out, this will be the recommended version. In addition, there is no more Oracle/BEA JRockit available for Java 7, use the official Oracle Java 7. JRockit was never working correctly with Lucene/Solr (causing index corrumption), so this should not be an issue. Please also review our list of JVM bugs: http://wiki.apache.org/lucene-java/JavaBugs

EDIT (as of 15 April 2014): The recently released Java 7u55 fixes the above bug causing index corrumption. This version is now the recommended version for running Apache Solr.
