             Summary: Affinity.mapKeyToNode() method throw "ArithmeticException: / by zero" for LOCAL cache
                 Key: IGNITE-2554
                 URL: https://issues.apache.org/jira/browse/IGNITE-2554
             Project: Ignite
          Issue Type: Bug
            Reporter: Artem Shutak
            Priority: Minor


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

The following code
{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");
        }
    }
{code}

Produce the following exception.

{noformat}
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
{noformat}

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

[Artem Shutak]

Hi Ken,

I've investigated the issue and a short answer is it's not a newbie issue.

Detailed answer is there is 2 possible ways to fix it (at least): a simple
fix and a not simple fix.

I need to do the simple fix by yourself because it's need for related issue.

The not simple fix is hard for newbie. May be it should be fixed as
separate issue.

By the way, I will add my investigation results to the ticket and you can
try to fix it according to my comments and provide a patch.

Thanks,
-- Artem --
