In order to make sure different BOE clusters are isolated (regarding Explorer), please set either the 'master.cluster.name' or the 'master.cluster.multicast.group' parameters (CMC : Explorer application's advanced configuration) with different values on each BOE cluster. (Number of running enabled Explorer Master servers in cluster: 0, Number of Hazelcast cluster members: 2)
