Joel Knighton commented on CASSANDRA-10952:
-------------------------------------------

You are correct - this looks to be a different issue than [CASSANDRA-10089]. 
I'm not immediately able to find the problem.

A few more pieces of information would be helpful:
1. Can you provide full logs from both a node that was already in the cluster 
and a bootstrapping node?
2. Is the bootstrapped node missing from all nodes in the cluster or just some?
3. What does nodetool status on a missing bootstrapped node report?

Thanks.

> This looks different than CASSANDRA-10089, so I create a new jira.
