Benjamin Lerer commented on CASSANDRA-11595:
--------------------------------------------
Let's not mix up everything. This ticket has been opened on the 3.0.x release
and the problem was caused by a 'too many open files' problem when C* was
trying to resize the file. The file ended up with a size of zero.
In that case there is unfortunatly nothing that can be done to correct the
problem before shutdown.
I think the safest choice here is to prevent C* from starting and to let the
administrator deal with the problem. As in this case the file is obviously
empty the solution to the problem is pretty clear.
[~andrew.tolbert] you are talking in my opinion of a different problem in the
same area that affect 2.1 where C* has probably crashed after the resize.
I will clause the ticket as {{Not A Problem}} as C* behaved as expected.
