> There are some parts of logic in Ignite that check whether two nodes are actually hosted on the same physical machine (e.g. excludeNeighbors flag in affinity function, load balancing for replicated cache, etc) and choose the appropriate behavior. These part can be tracked by usages of IgniteNodeAttributes#ATTR_MACS attribute.
> I've tried to emulate distributed environment in tests by overriding ATTR_MACS with random UUID. This caused mass consistency failures in basic and Full API tests. We should investigate this: probably, many bugs are hidden by the fact that nodes are always started on the same physical machine in our TeamCity tests.
