Hi There
I have been checking out the latest (8.8.0) SolrCloud database (using
Zookeeper 3.6.2) against our application which talks to Solr via the Solr
API (I am not too sure of the details as I am not a java developer
unfortunately!). The software has Solr 8.7.0/ZooKeeper 3.6.2 libraries
'embedded'.
When our application sends a query to the SolrCloud 8.8.0 database it
generates this error:
2021-02-05 05:36:42,644 INFO

If try the same test pointing to a SolrCloud 8.7.0/Zookeeper 3.6.2 all is
well and search returns results. I was wondering if there is some additional
config required for Solr 8.8.0 to be connected to via ZooKeeper?
When I point our application to a Solr 8.8.0 single server (non-cloud) it
connects ok and returns results. The issue just seems to be with SolrCloud.
Many Thanks
Matthew
