Data Hub Module

(CDQE-61011) In the Dashboard for Data Hub Visualization, an upgraded Data Hub model may return an error when accessing certain widgets (for example, Top Entities by Property Value). The error contains this message: "unexpected docvalues type NONE for field '<name>' (expected one of [SORTED, SORTED_SET]). Use UninvertingReader or index with docvalues."
The workaround for this problem is to rebuild the index for the model:
1. Point a Web browser to http://<servername>:<port>/jmx-console/ (port is 8080 by default).
2. In Domain: com.pb.spectrum.hub, click com.pb.spectrum.hub:service=HubConfigManager.
3. Scroll down to rebuildIndexes, provide the modelName in the Value box, and click Invoke. This will start a job that replaces the index on all the indexed properties. The progress for this job will be logged to the wrapper.log file. When the indexing is complete, the system is ready for use; no restart is required.
