["David Capwell (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-15685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17121396#comment-17121396 ] 

David Capwell commented on CASSANDRA-15685:
-------------------------------------------

[~bdeggleston] [~marcuse] could we get your thoughts on this?  preview repair isn't allowed to be run concurrently with IR, but IR completes before the message is handled on the participant; the below is impacted by this race condition.

{code}
nodetool repair foo bar
# does not look to be running concurrently with the above IR, since it was notified of success
# but the commit message may not have been seen yet which cause this to be concurrent with the above
nodetool repair foo bar --validate
{code}
