This means that communication SPI was not able to load shared memory library
and use shared memory communication. Most likely ignite-shmem-1.0.0.jar is
not on classpath and IGNITE_HOME variable is not set.

Node is still functional in this case, because it transparently switches to
TCP communication. This can potentially cause slight performance degradation
in communication between nodes located on one physical box. If you don't
observe this, warning can be safely ignored.
