On Solr 4.9.1 with core discovery, I seem to be having trouble with core swaps not persisting through a full Solr restart.
I apologize for the fact that this message is lean on details ... I've seen the problem twice now, but I don't have any concrete before/after information about what's in each core.properties file. I am attempting to set up the scenario again and gather that information. The entire directory structure is set up as a git repo, so I will be able to tell if any files (like core.properties) are modified for the rebuild/swap that I have started. The repo shows no changes at the moment, but I have done several of these rebuild/swap operations, so even if core.properties is being correctly updated, it might just have landed back on the original configuration. I have another copy of my index using Solr 4.7.2 with the old solr.xml format that seems to have no problems with core swapping and persistence. That works differently, though -- all cores are defined in solr.xml rather than with core.properties files. When I first set up these Solr instances, I don't recall having this problem, but full Solr restarts are really rare, so it's possible I just didn't create the right circumstances. Thanks, Shawn
