Jeff Jirsa commented on CASSANDRA-11995:
----------------------------------------
[~blambov] - I do think there's a few areas for improvement, though this is the
low hanging fruit of it. The one case where I was able to see this myself was
in a test environment where failures were expected (and indeed, injected), but
based on the descriptions above, I believe happens on any unclean shutdown
triggered during startup.
I'd personally like to commit this as an intermediate step, and not try to fix
ALL of the potential problems at once (I think this removes the most obvious
cause, and does it with very little risk). Are you ok with that, and we can
open some follow-up tickets as they arise?
