I'm prototyping something with Spring-Boot 1.2.7.RELEASE and Apache Ignite 1.4.0 and noticed something a little odd, maybe it's a just a logging configuration.
It looks like Apache Ignite is trying to start twice with Spring? If I comment out the SpringApplication.run line then it looks like it only starts once. Maybe I'm not using Spring with Apache Ignite correctly?

Actually Ignite starts once in both cases (with commented and uncommented SpringApplication.run line). Each Ignite node prints out current topology snapshot, but I see only one line about it in log:
Topology snapshot [ver=14, servers=2, clients=0, CPUs=8, heap=3.7GB]
These are not "two instances", but two ways of how Ignite logs startup banner - one with STDOUT and another one with a built-in logger.
Just add ignite-slf4j dependency and use setGridLogger method of IgniteConfiguration to override the default logger - this message will disappear.
