Description

Affinity.mapKeyToNode() method throw "ArithmeticException: / by zero" for LOCAL cache.

The following code

    public static void main(String[] args) {
        try (Ignite ignite = Ignition.start(new IgniteConfiguration())) {
            CacheConfiguration cc = new CacheConfiguration();

            cc.setCacheMode(LOCAL);
            cc.setName("myCache");

            ignite.getOrCreateCache(cc);

            ignite.affinity("myCache").mapKeyToNode("myKey");
        }
    }

Produce the following exception.

Exception in thread "main" java.lang.ArithmeticException: / by zero
	at org.apache.ignite.internal.processors.cache.affinity.GridCacheAffinityImpl.mapKeysToNodes(GridCacheAffinityImpl.java:210)
	at org.apache.ignite.internal.processors.cache.affinity.GridCacheAffinityImpl.mapKeyToNode(GridCacheAffinityImpl.java:187)
	at main

The issue is cctx.discovery().cacheAffinityNodes(cctx.name(), topVer) returns empty nodes collection.

If cache started on node start then there is no exception.
