Jeff Jirsa commented on CASSANDRA-10393:
[~jippignu] - do you recall if this issue is solved, or if you worked around it
somehow? The impacted version {{2.2.1}} is quite old at this point, but still
getting fixes if we can repro. If we can't reliably repro it with latest 2.2,
do you mind if we close this as can't-reproduce?
