------------------------------------------
Summary: Race in SplitAwareTopologyValidator on activator and
server node join
Key: IGNITE-6519
URL: https://issues.apache.org/jira/browse/IGNITE-6519
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.
