Apache Solr Release Notes
|
||||
|
||||
Introduction
|
||||
------------
|
||||
Apache Solr is an open source enterprise search server based on the Apache Lucene Java
|
||||
search library, with XML/HTTP and JSON APIs, hit highlighting, faceted search,
|
||||
caching, replication, and a web administration interface.
|
||||
|
||||
See http://lucene.apache.org/solr for more information.
|
||||
|
||||
|
||||
Getting Started
|
||||
---------------
|
||||
You need a Java 11 VM or later installed.
|
||||
In this release, there is an example Solr server including a bundled
|
||||
servlet container in the directory named "example".
|
||||
See the Solr tutorial at https://lucene.apache.org/solr/guide/solr-tutorial.html
|
||||
This file lists Solr's raw release notes with details of every change to Solr.
|
||||
Most people will find the solr-upgrade-notes.adoc file more approachable.
|
||||

Upgrade Notes
|
||||
----------------------
|
||||
|
||||
* LUCENE-8738: Move to Java 11 as minimum Java version.
|
||||
(Adrien Grand, Uwe Schindler)
|
||||
|
||||
* SOLR-12055 introduces async logging by default. There's a small window where log messages may be lost
|
||||
in the event of some hard crash. Switch back to synchronous logging if this is unacceptable, see
|
||||
see comments in the log4j2 configuration files (log4j2.xml by default).
|
||||
|
||||
* SOLR-12891: MacroExpander will no longer will expand URL parameters inside of the 'expr' parameter (used by streaming
|
||||
expressions) Additionally, users are advised to use the 'InjectionDefense' class when constructing streaming
|
||||
expressions that include user supplied data to avoid risks similar to SQL injection. The legacy behavior of
|
||||
expanding the 'expr' parameter can be reinstated with -DStreamingExpressionMacros=true passed to the JVM at startup
|
||||
(Gus Heck).
|
||||
|
||||
* SOLR-13324: URLClassifyProcessor#getCanonicalUrl now throws MalformedURLException rather than hiding it. Although the
|
||||
present code is unlikely to produce such an exception it may be possible in future changes or in subclasses.
|
||||
Currently this change should only effect compatibility of custom code overriding this method (Gus Heck).
|
||||
|
||||
* SOLR-13323: The unused package org.apache.solr.internal.csv.writer and associated classes/tests that were easily
|
||||
confused with but not used by org.apache.solr.response.CSVWriter (or any other code) have been removed (Gus Heck)
|
||||
|
||||
* SOLR-7530: TermsComponent's JSON response format was changed so that "terms" property carries per field arrays by default
|
||||
regardless of distrib, terms.list, terms.ttf parameters. This affects JSON based response format but not others
|
||||
(Munendra S N, Mikhail Khludnev)
|
||||
|
||||
* SOLR-13596: Deprecated GroupingSpecification methods are removed. (Munendra S N)
|
||||
|
||||
* SOLR-13649: Property 'blockUnknown' of BasicAuthPlugin and JWTAuthPlugin now defaults to 'true'. This change is backward
|
||||
incompatible. To achieve the previous default behavior, explicitly set 'blockUnknown':'false' in security.json
|
||||
(marcussorealheis, janhoy, shalin)
|
||||
|
||||
* SOLR-11266: default Content-Type override for JSONResponseWriter from _default configSet is removed. Example has been
|
||||
provided in sample_techproducts_configs to override content-type. (Ishan Chattopadhyaya, Munendra S N, Gus Heck)
|
||||
|
||||
* SOLR-13593 SOLR-13690 SOLR-13691: Allow to look up analyzer components by their SPI names in field type configuration. (Tomoko Uchida)
|
||||
|
||||
* SOLR-13854, SOLR-13858: SolrMetricProducer / SolrInfoBean APIs have changed and third-party components that implement these APIs need to be updated. (ab)
|
||||
|
||||
* SOLR-13783: In situations where a NamedList must be output as plain text, commas between key-value pairs will now be
|
||||
followed by a space (e.g. {shape=square, color=yellow} rather than {shape=square,color=yellow}) for consistency with
|
||||
other java.util.Map implementations based on AbstractMap (Chris Hennick).
|
||||
|
||||
* SOLR-13817: Legacy SolrCache implementations (LRUCache, LFUCache, FastLRUCache) have been removed.
|
||||
Users have to modify their existing configurations to use CaffeineCache instead. (ab)
|
||||
|
||||
* SOLR-14092: Deprecated BlockJoinFacetComponent and BlockJoinDocSetFacetComponent are removed
|
||||
Users are encouraged to migrate to uniqueBlock() in JSON Facet API. (Mikhail Khludnev)
|
||||
|
||||
* SOLR-13985: Solr's Jetty now binds to localhost network interface by default for better out of the box security.
|
||||
Administrators that need Solr exposed more broadly can change the SOLR_JETTY_HOST property in their Solr include
|
||||
(solr.in.sh/solr.in.cmd) file. (Jason Gerlowski, David Smiley, Robert Muir)
|
||||
|
||||
* SOLR-14147: Solr now runs with the java security manager enabled by default. Administrators that need to run Solr with Hadoop will need to disable this feature by setting SOLR_SECURITY_MANAGER=false in the environment or in one of the Solr init scripts. Other features in Solr could also break. (Robert Muir, marcussorealheis)
|
||||
|
||||
* SOLR-14118: Solr embedded zookeeper only binds to localhost by default.
|
||||
This embedded zookeeper should not be used in production. If you rely
|
||||
upon the previous behavior, then you can change the clientPortAddress
|
||||
in solr/server/solr/zoo.cfg (Robert Muir)
|
||||
(No changes)
|
||||
|
||||
Improvements

Upgrade Notes
|

---------------------
|
||||
|
||||
* SOLR-14026: Upgrade Jetty to 9.4.24.v20191120 and dropwizard to 4.1.2 (Erick Erickson)
|
||||
|
||||
* SOLR-14092: BlockJoinFacetComponent is marked for deprecation and will be removed in 9.0.
|
||||
Users are encouraged to migrate to uniqueBlock() in JSON Facet API. (Mikhail Khludnev)
|
||||
|
||||
* SOLR-13983: Process execution is removed from SystemInfoHandler. A best-effort attempt to
|
||||
execute "uname -a" and "uptime" on non-Windows platforms is no longer made. (rmuir)
|
||||
|
||||
* SOLR-14095 introduces a change in the format used for the elements in the Overseer queues and maps (see the Jira
|
||||
issue for details on the reasons for the change). This queue is used internally by the Overseer to reliably handle
|
||||
operations, to communicate operation results between the Overseer and the coordinator node, and by the
|
||||
REQUESTSTATUS API for displaying information about async Collection operations.
|
||||
This change won’t require you to change any client-side code you should see no differences on the client side,
|
||||
however, it does require some care when upgrading an existing SolrCloud cluster:
|
||||
- If you are upgrading Solr with an atomic restart strategy:
|
||||
- If you don’t use async or REQUESTSTATUS operations, you should be able to restart and not see any issues.
|
||||
- If you do use Collection API operations:
|
||||
1. pause Collection API operations
|
||||
2. cleanup queues (https://lucene.apache.org/solr/guide/8_3/collections-api.html#examples-using-deletestatus)
|
||||
if you use async operations
|
||||
3. upgrade and restart the nodes
|
||||
- If you are upgrading Solr with a rolling restart strategy:
|
||||
- If you don’t use Collection API operations, you should be able to do a rolling restart and not see
|
||||
any issues.
|
||||
- If you do use Collection API operations, but you can pause their use during the restart the easiest
|
||||
way is to:
|
||||
1. pause Collection API operations
|
||||
2. upgrade and restart all nodes
|
||||
3. cleanup queues (https://lucene.apache.org/solr/guide/8_3/collections-api.html#examples-using-deletestatus)
|
||||
if you use async operations
|
||||
4. Resume all normal operations
|
||||
- If you use Collection API operations and can’t pause them during the upgrade:
|
||||
1. Start 8.5 nodes with the system property: `-Dsolr.useUnsafeOverseerResponse=deserialization`. Ensure the
|
||||
Overseer node is upgraded last
|
||||
2. Once all nodes are in 8.5 and once you don’t need to read old status anymore, restart again removing the
|
||||
system property
|
||||
If you prefer to keep the old (but insecure) serialization strategy, you can start your nodes using the
|
||||
property: `-Dsolr.useUnsafeOverseerResponse=true`. Keep in mind that this will be removed in future version of Solr.
|
||||
|

* SOLR-13808: add cache=false into underneath BoolQParser's filter clause or {"bool":{"filter":..}} to avoid caching in
