Hello, Igniters.
I found really confusing results of the simple test.
Data from the in-memory cache are vanished after change cluster state to
INACTIVE/ACTIVE.
Is this a bug or expected behavior?
```
public class ClusterDeactivateTest extends GridCommonAbstractTest {
String name = "my-cache";
/** */
@Test
public void testDataPresent() throws Exception {
IgniteEx i = startGrid(0);
i.createCache(name).put(1L, 1L);
assertEquals(1L, i.cache(name).get(1L));
i.cluster().state(ClusterState.INACTIVE);
i.cluster().state(ClusterState.ACTIVE);
assertEquals(1L, i.cache(name).get(1L)); //Assertion error here!
}
}
```
