Andrey Velichko commented on IGNITE-1018:
-----------------------------------------

Ignite\modules\core\src\main\java\org\apache\ignite\internal\cluster\IgniteClusterImpl.java
public <K, V> ConcurrentMap<K, V> nodeLocalMap() {
удалил блокировку guard() / unguard()
 
ignite\examples\src\main\java\org\apache\ignite\examples\misc\lifecycle\LifecycleExample.java
Добавил в пример счетчик событий

 +             IgniteCluster cluster = ignite.cluster();
 +             ConcurrentMap map = cluster.nodeLocalMap();
 +             Integer val = (Integer)map.getOrDefault(evt, 0);
 +             map.put(evt, val + 1); // event counter

> Currently {{IgniteCluster.nodeLocalMap()}} method is guarded by gateway like all others.
But this is just a local concurrent map which is already available at the moment LifecycleEventType.BEFORE_NODE_START
is processed, so I think it will be good to make it available in lifecycle bean.
> This can be useful if user needs to initialize some resources and put them to node local
map before node is started.
