> org.apache.ignite.internal.util.GridConcurrentHashSet cannot be cast to

> {code}
> There are 2 problems in the test.
> 1) We don't wait for final topology version is set on all nodes and start
> checking discovery caches immediately after grids starting. It leads to
> possible NullPointerException while accessing to discovery caches history.
> 2) We don't use explicit assertEquals(String, Object, Object) related to
> comparing Objects, while Java can choose assertEquals(String, String) method
> to compare discovery cache fields which we're getting in runtime using
> reflection.
