Marcus Eriksson updated CASSANDRA-15553:
----------------------------------------
Test and Documentation Plan: new in-jvm dtests and cci runs
Status: Patch Available (was: Open)
[patch|https://github.com/krummas/cassandra/commits/marcuse/previewrepairfix],
[cci|https://circleci.com/workflow-run/9ee445fb-8ac7-44e3-b74e-345734b312c3]
Patch includes sstables from finalized sessions in the repaired set. Also adds
a state change listener interface to `LocalSessions` which preview repair
`RepairSession` listens to to fail any intersecting preview repairs.
> Preview repair should include sstables from finalized incremental repair

> Key: CASSANDRA-15553
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15553
> Project: Cassandra
> Issue Type: Bug
> Components: Consistency/Repair
> Reporter: Marcus Eriksson
> Assignee: Marcus Eriksson
> Priority: Normal
> Fix For: 4.0-alpha
>
>
> When running a preview repair we currently grab all repaired sstables,
> problem is that we depend on compaction to move the sstables from pending to
> repaired so we might have different data marked repaired on different nodes.
> Including any sstables from finalized incremental repair sessions as repaired
> will solve this.
> Another problem is that validations don't start at exactly the same time on
> different nodes, so if an incremental repair finishes while the preview
> repair is running we might also validate the wrong repaired set. We should
> fail the preview repair if an intersecting incremental repair finishes during
> the preview repair.
