  • Use external management tools to control Fusion configurations

    Many of the values in conf/fusion.properties can now be set using environment variables, enabling you to set them using systemd, Docker, Kubernetes, and so on. Default values are also provided. For example, in api.port = ${API_PORT:-8765}, the default value is 8765 unless API_PORT is defined.

    Note that ZOOKEEPER_PORT cannot not be used, and value of zookeeper.port in fusion.properties must be the same as the value of clientPort in conf/zookeeper/zoo.cfg.

  • Improved connectors functionality

    • Kerberos support in the Web connector and the Jive connector.

    • The OneDrive connector can now crawl user-specific drives.

    • Some connectors now give you the option to index metadata about documents that were discarded because they were too large or too small using the new f.index_items_discarded/Index discarded document metadata parameter. A new field, _lw_skipped_reason_s, indicates the reason that the document was skipped during indexing. The new key is available for these connectors:

Other changes

  • The synonyms collection has been replaced with the new query_rewrite collection.

  • For faster download of the Fusion package, the folder apps/solr-dist which contained the full Apache Solr distribution has been removed. If you want to access contrib files, scripts, or related items, you must download the Apache Solr distribution separately from the Apache Solr project.
