Subject [ANNOUNCE] Apache Solr 6.6.1 released
Date Fri, 08 Sep 2017 02:46:32 GMT
7 September 2017, Apache Solr™ 6.6.1 available

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.

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.
