Ariel Weisberg commented on CASSANDRA-14841:
--------------------------------------------
Why would this block repairs and why would it stop you from monitoring repairs?
Wouldn't you use nodetool repair admin to monitor repairs?
For repair it is just a history table. It's only populated after repair has
already occurred.
I'm not sure users can alter the schema of the distributed system tables.
@imaleksey is that actually possible?
