------------------------------------------
Summary: 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: Core
Reporter: Jeremiah Jordan
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).
