Title: Apache Solr™ 6.6.1 available category: solr/news URL: save_as:
The Lucene PMC is pleased to announce the release of Apache Solr 6.6.1
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 6.6.1 is available for immediate download at: https://lucene.apache.org/solr/mirrors-solr-latest-redir.html
This release includes 15 bug fixes since the 6.6.0 release. Some of the major fixes are:
Standalone Solr loads UNLOADed core on request
ParallelStream should set the StreamContext when constructing SolrStreams
CloudSolrStream.toExpression incorrectly handles fq clauses
CoreContainer.load needs to send lazily loaded core descriptors to the proper list rather than send them all to the transient lists
Creating a core should write a core.properties file first and clean up on failure
Clean up a few details left over from pluggable transient core and untangling
Provide a way to know when Core Discovery is finished and when all async cores are done loading
CDCR bootstrapping can get into an infinite loop when a core is reloaded
SolrJmxReporter is broken on core reload. This resulted in some or most metrics not being reported via JMX after core reloads, depending on timing
Creating a core.properties fails if the parent of core.properties is a symlinked directory
StreamHandler should allow connections to be closed early
Certain admin UI pages would not load up correctly with kerberos enabled
Fix DOWNNODE -> queue-work znode explosion in ZooKeeper
Upgrade to Hadoop 2.7.4 to fix incompatibility with Java 9
Fix bin/solr.cmd so it can run properly on Java 9
Furthermore, this release includes Apache Lucene 6.6.1 which includes 2 bug fixes since the 6.6.0 release.
