Subject Re: Is it safe to upgrade 2.2.6 to 3.0.13?
Date Sat, 20 May 2017 10:31:21 GMT

can you elaborate a bit more? I have seen a schema change being pushed, but
that was just the first restart. After that, everything has been smooth so
far (including several schema changes, all of them verified via "describe").

Thanks!
Stefano
