Here is my +1 ~ SUCCESS! [0:50:06.728441] In addition to the smoke test, I built a Docker image from solr-8.8.1.tgz locally and verified: a. A rolling upgrade of a 3-node 8.7.0 cluster to the 8.8.1 RC completes successfully w/o any NPEs or weirdness with leader election / recoveries. b. The base_url property is stored in replica state after the upgrade c. A basic client application built with SolrJ 8.7.0 can load cluster state info directly from ZK and query the 8.8.1 RC1 servers. d. Same client app built with SolrJ 8.8.0 works as well. As this bug-fix release is primarily needed to address a SolrJ back-compat break (SOLR-15145) and unfortunately our smoke tester framework does not test for backcompat of older SolrJ against the RC, I ask others to please test rolling upgrades of servers (ideally multi-node clusters) running pre-8.8.0 to this RC if possible. Also, please try client applications that are using an older SolrJ, esp. those that load cluster state directly from ZK. Best regards, Tim
