You could also pull TWCS out of the version of Cassandra you want to
deploy, fix the imports and change the package name. Then you've got the
same version as OSS, just under the name you're using in 2.1. Once you've
moved to 3.11, you can switch to the OSS version.

That sounds very interesting Alex, so just to be sure I understand, it was
like this
1 - you had 2.1 cluster running with the 2.1 version jar
2 - you upgraded to 3.0, starting the cluster with the 3.0 version jar that
has the same strategy name
3 - you changed the compaction strategy to use the

Hey
I have a 2.11.4 cluster with tables that are defined with twcs, using
jeff's jar

All working great, but now I want to upgrade to 3.11, and I have a problem,
cassandra won't start, it fails on the following error
