Fusion Server 5.1.3 Release Notes


Release date: 18 June 2020

Component versions:

Solr 8.4.1

ZooKeeper 3.5.6

Spark 2.4.5

New Features


  • Fusion 5.1.3 adds the Connector Plugins Repository API. This API is used to install and update connector plugins from the built-in plugin repository. For example, the following command describes a successful installation of a connector plugin with the API:

    curl -u admin:Password123 -X POST "http://fusion-cluster:6764/connectors/plugins?id=lucidworks.fs"
      "pluginId" : "lucidworks.fs",
      "status" : {
        "action" : "INSTALL",
        "status" : "SUCCESS",
        "message" : "Plugin lucidworks.fs was installed successfully."



  • Support for service:// and extservice:// is added to the REST Query Index Stage. This is consistent with the Rest Call Jobs, which supports calls to other Kubernetes services. For example, service://<serviceName>/<path> or extservice://<serviceName>/<path>.

  • The Solr Subquery query pipeline stage now supports grouped results from Solr grouped queries. Access the groupValue and the documents for a group in the Javascript stage:

    groupValue = ctx.get("subquery-results").grouped.get("Category_s").getGroups().get(0).getGroupValue()
    docs = ctx.get("subquery-results").grouped.get("Category_s").getGroups().get(0).getDoclist().docs

    Now, Solr Subquery’s SearchResponse has a new field, grouped, which is a map of group field names to GroupCollections.

Other changes


  • The Push connector is removed. As an alternative, directly access the index endpoints.

  • Java-based services have moved to distroless Docker images. As a result, debugging tools must be run remotely.

Bug fixes


  • IMPORTANT: Fixed a bug that prevented the FTP connector from working.

  • Fixed a bug that caused long data values in job statuses to exceed the allowed character limit.
