Benjamin Lerer commented on CASSANDRA-11595:
--------------------------------------------
[~n0rad] there might be other scenario that result in an empty CommitLog files
and not all of them need to be handle in the same way.
The problem is that C* does not know what has happend before or what the
administrator is trying to do. In this case it always safer to let the
administrator, who know the full context to handle the problem.
Your real problem is CASSANDRA-11594. Without it you will rarely bump into an
empty CommitLog segment.
