Subject [jira] [Commented] (CASSANDRA-8217) Fail snapshot based repair if Merkle tree does not use the same snapshot
Date Wed, 29 Oct 2014 22:54:33 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14189198#comment-14189198

Yuki Morishita commented on CASSANDRA-8217:
-------------------------------------------

I agree this can be useful.
We use repair sesion ID for snapshot name right now, so I think what we need to do is making
it somehow unique among each snapshot.

> Snapshot based repair rely on having a snapshot on each replica. If for some reason,
snapshot is not found or is different, we should fail the repair. This will avoid streaming
lot of data around.
