Subject Re: Running repair while Cassandra upgrade 2.0.X to 2.1.X
Date Mon, 11 Dec 2017 23:47:23 GMT
That ticket says that streaming SSTables that are older versions is
supported. Streaming is only one component of repairs, and this ticket
doesn't talk about repair at all, only bootstrap. For the most part it
should work but as Alain said, it's probably best avoided. Especially if
you can avoid it (your cluster isn't so huge it's going to take days to
upgrade). Just upgrade your nodes, run and re-run upgradesstables until it
stops kicking off upgrade compactions, then re-start your repairs.‚Äč
