> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.1
> Reporter: Alexandr Kuramshin
> Assignee: Alexandr Kuramshin
>
> The following sequence may occur:
> 1. {{SplitAwareTopologyValidator}} detects split, gets {{NOTVALID}} and
> returns false from {{validate()}}
> 2. Activator node joins and {{SplitAwareTopologyValidator}} gets {{REPAIRED}}
> 3. Server node joins from other DC and it makes
> {{SplitAwareTopologyValidator}} gets {{VALID}}
> 4. Then the server node left the cluster and {{SplitAwareTopologyValidator}}
> should return false from {{validate()}} in cause of next split
> But current implementation makes {{SplitAwareTopologyValidator}}
> auto-{{REPAIRED}}. Actually if the activator node will being forgotten to
> leave the cluster it may automatically repair a split many times. But it
> supposed to be manual operation.
