Hi:
I figured I'd share this with you FYI. I've not seen this happen before and I've POSTed several revisions to solrconfig.xml and schema.xml. However, I just launched an instance of the single node DSE AMI I created a while back started DSE and issued some queries. Then I wanted to apply the core updates I've made on other nodes and this happened.
I applied the updates again, and no errors occurred that time, so I'm proceeding. But, it seems operating on a closed IndexWriter is not a good thing and I wanted to at least provide some of the log messages and the stack trace to make you aware:
