---------------------------------------

             Summary: Improve error message when requested topology version was preempted
from Discovery Cache
                 Key: IGNITE-8753
                 URL: https://issues.apache.org/jira/browse/IGNITE-8753
             Project: Ignite
          Issue Type: Improvement
            Reporter: Sergey Chugunov


When a lot of nodes try to join cluster at the same time (which is common when ZookeeperDiscoverySpi
is used), size of Discovery Cache may be exhausted so next node won't find topology version
it needs to proceed with joining.

For now exception is thrown in this situation, we need to improve its message with suggestion
to check DISCOVERY_HISTORY setting.
