Tyler Hobbs commented on CASSANDRA-8462:
----------------------------------------

[~philipthompson] I'm guessing the dtests don't cover restarting nodes in a mixed-version cluster.  Would it be possible to add some test coverage for that?

> Added a 2.1.2 node to a cluster running 2.0.11. Didn't make any schema changes. When I tried to reboot one of the 2.0 nodes, it failed to boot with this exception. Besides an obvious fix, any workarounds for this?
