C. Scott Andreas updated CASSANDRA-7530:
----------------------------------------
Component/s: Repair
> Repair should be allowed in mixed version clusters
> --------------------------------------------------
>
> Key: CASSANDRA-7530
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7530
> Project: Cassandra
> Issue Type: Improvement
> Components: Repair
> Reporter: Jeremiah Jordan
> Priority: Major
> Labels: ponies
>
> As we try to improve the ops experience for large clusters (or cautious
> people), we need to make it so repair works across major version upgrades.
> Currently you have to be able to upgrade all of your nodes and then run a
> full repair, within the gc_grace window.
> The recent ability to stream old sstables makes this a little better, as you
> don't have to also run upgradesstables first.
> It would be really good if we could let people pause their upgrade of 1000
> nodes to run some repairs. Or to upgrade one DC and test the new major
> version for a while (while still running repairs).
