I occasionally see this error in our logs: 2017-01-05 20:48:46.664 ERROR (SolrConfigHandler-refreshconf) [c:sial-catalog-material s:shard2 r:core_node2 x:sial-catalog-material_shard2_replica1] o.a.s.s.IndexSchema This IndexSchema is not mutable.
None of our indexes are mutable, nor are we trying to use the managed schema features. It doesn't seem to cause a problem, but I want to understand where this ERROR is coming from. It may be related to the use of the Config API which we use to dynamically set properties and to configure the CDCR Request handlers. I don't see anything in the Config API docs that limits its use to collections with managed schemas, moreover the API seems to work fine. I don't see SolrConfigHandler defined in the solrconfig.xml file We have been using the same basic schema file since Solr 3.* upgrading the schema and config as needed. I've only seen this error since migrating to Solr 6.2 -- This message and any attachment are confidential and may be privileged or otherwise protected from disclosure.
