------------------------------------------------------------------------
I am having the same issue, that is the entire stack trace. Is there some way
that I can get more of the information that you need? A debug build?
I am using 3.7, and I am trying to upgrade from 2.1. FYI my cluster is a
single node cluster with no replication (I know that is very bad).
where do I get the build where CASSANDRA-11988 is applied? Also is there a
way for me to enable more detailed logging that would help you to diagnose this?
