ClusterServiceImpl
calls this method,
when handleJoinRequest method is called. By this way, we can check the logic we want
by implementing this method. Implementation should throw required exception, with a valid
message which explains rejection reason.Copyright © 2015 Hazelcast, Inc.. All Rights Reserved.
