----------------------------------
Summary: Setting different MAC addresses to nodes in test
environment causes mass test fail
Key: IGNITE-8646
URL: https://issues.apache.org/jira/browse/IGNITE-8646
Project: Ignite
Issue Type: Bug
Reporter: Ivan Rakov
Fix For: 2.6
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.
