Hi Robert, sorry, I am using our own internal terminology :-)
The entire cluster was upgraded. All 3 nodes of that cluster are on 2.0.8 now. About the issue: To me it looks like there is something wrong in the Memtable class. Some very special edge case on CFs that are updated rarely. I cant say if it is new to 2.0 or if it already existed in 1.2. About running mixed versions: I thought running mixed versions is ok. Running repair with mixed versions is not though. Right? kind regards, Christian On Mon, Jun 16, 2014 at 7:50 PM, Robert Coli <rc...@eventbrite.com> wrote: > On Sat, Jun 14, 2014 at 1:02 PM, horschi <hors...@gmail.com> wrote: > >> this week we upgraded one of our Systems from Cassandra 1.2.16 to 2.0.8. >> All 3 nodes were upgraded.
