> Key: IGNITE-11996
> URL: https://issues.apache.org/jira/browse/IGNITE-11996
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.7.5
> Reporter: Ivan Pavlukhin
> Assignee: Ivan Pavlukhin
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Assertion error occurs in a following code:
> {code}
> boolean removed = partDataStores.remove(p, store);
> assert removed;
> {code}
> It asserts that a partition store must be removed from a map here. But in
> practice a removal can occur at least in 2 places: node stop and partition
> eviction. Employed synchronization is not sufficient to guarantee that a
> removal happens exactly once.
> The issue is reproduced in {{IgniteSqlQueryMinMaxTest}} from time to time.
