> URL: https://issues.apache.org/jira/browse/IGNITE-10671
> Project: Ignite
> Issue Type: Bug
> Reporter: Pavel Voronkin
> Assignee: Pavel Voronkin
> Priority: Critical
> Fix For: 2.8
>
> Attachments: WalCompactionSwitchOverTest.java
>
>
> Race is painful when you switch your cluster from walCompaction=false to
> walCompaction=true.
> The same FileCompressor instance will use different segmentAwares due to
> start0() is called twice which leads to inconsistent behaviour and errors
> during compaction, basically we will try to archive files twice concurrently.
> See reproducer in attachment.
