We use Ignite to manage some caches, http session clustering... in a java web application using spring in a tomcat8 server. So it seems to start 2 ignite instances one which start with spring :
<beans:bean id="cacheManager" class="org.apache.ignite.cache.spring.SpringCacheManager">
<beans:property name="igniteInstanceName" value="hibernate-grid"/>
</beans:bean>
And another that don't join the cluster because there is no configuration for it and its name is CacheManager_0.
I have in catalina.out logs
org.apache.ignite.logger.java.JavaLogger.info Performance suggestions for grid 'CacheManager_0' (fix if possible)
And in application logs
INFO o.a.i.i.IgniteKernal%hibernate-grid:117 - IgniteConfiguration [igniteInstanceName=hibernate-grid,...
So I imagine that tomcat8 launch ignite grid with no configuration. Is there any way to avoid that ?
