Hello, We're creating a SolrCloud in AWS and attempting to use autoscaling to add replicas during nodeAdded/nodeLost. This was working fine for us until we started creating collections specifying core properties (e.g. /solr/admin/collections?action=CREATE&property.synonyms_datasource=REDACTED). It seems that when the nodeLost/Added trigger fires the properties don't manifest in the core create invocation and we get errors like the following:
products_20180904200015_shard1_replica_n39: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not load conf for core products_20180904200015_shard1_replica_n39: Can't load schema schema.xml: No system property or default value specified for synonyms_datasource value:jdbc/${synonyms_datasource} The autoscaling API also doesn't appear to have a way to set the properties when we create the triggers. Are we missing something or is this not supported at this time? I couldn't find a relevant JIRA or other documentation or solr-user discussion on this. thanks, JiM
