MAPSET_INCOMPATIBLE_PARTITION_NUM_CWOBJ4900=CWOBJ4900E: Domain {0} is not going to send updates to domain {1} for map set {2} from ObjectGrid {3} because of a mismatch in the number of partitions. The map set is configured for {4} partitions in domain {0} and {5} partitions in domain {1}.
Explanation
The map set must be configured with the same number of partitions in each domain in order to achieve a multi-data center topology.
User response
Stop the containers that host the map set in one of the domains. Restart these containers with a deployment policy that contains the map set with the proper number of partitions.
