I guess you'll have to hop through 3.0 first. We did upgrade from 2.1 to 3.0 by including a twcs.jar built against 3.0 and then altering the table compaction to use the built-in one, then finally removing the custom jar. We had to tweak it a bit for 3.0.15 at the time: https://github.com/a1exsh/twcs/tree/cassandra-3.0.x Regards, -- Alex
