Description

Assertion error occurs in IgniteCacheOffheapManagerImpl#destroyCacheDataStore in a following code:

boolean removed = partDataStores.remove(p, store);

assert removed;

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.
