I have a 3 zookeeper ensemble and 3 solr nodes running version 7.4.0. Recently I had to restart one node and after I did that it started throwing this exception.

It is VERY weird for instanceDir to be under the configsets directory. Especially for SolrCloud. I know you're in cloud mode because the ZK-related classes are heavily mentioned in the stacktrace.
Can you share the entire solr.log file after a restart? If that directory really is the instanceDir, there should be a core.properties file. What are its contents?
Did you use the service installer script? If you did, having an instanceDir underneath configsets is even MORE strange.
Thanks, Shawn
