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.

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,
