Subject Ignite client near cache conflicts with server distributed cache
Date Wed, 04 May 2016 14:37:28 GMT
Based on the discussion in Gitter it was proposed to ask a question here.

package experiments.ignite;

import org.apache.ignite.Ignite;
import org.apache.ignite.Ignition;
import org.apache.ignite.configuration.CacheConfiguration;
import org.apache.ignite.configuration.IgniteConfiguration;
import org.apache.ignite.configuration.NearCacheConfiguration;

public class ClientNearCache {

    public static void main(String[] args) {
        final CacheConfiguration<String, String> cacheConfiguration = new
CacheConfiguration<>("sample");

        final IgniteConfiguration igniteConfiguration = new
IgniteConfiguration()
                .setGridName("experiments")
                .setCacheConfiguration(cacheConfiguration);

        Ignition.setClientMode(true);
        final Ignite client = Ignition.start(igniteConfiguration);
        client.createNearCache("sample", new NearCacheConfiguration<>());
    }
}


The code above fails with the following error (there is a server node
running in another process):

Caused by: class org.apache.ignite.IgniteCheckedException: Failed to start
near cache (a cache with the same name without near cache is already
started)
	at
org.apache.ignite.internal.IgniteKernal.checkNearCacheStarted(IgniteKernal.java:2593)
	at
org.apache.ignite.internal.IgniteKernal.createNearCache(IgniteKernal.java:2545)
	... 6 more

My expectations would be, that according to
https://apacheignite.readme.io/docs/clients-vs-servers#creating-distributed-caches,
calling Ignition.start(igniteConfiguration) first time, will create a
distributed server cache. And client.createNearCache() will create the near
cache for that specific node's client.

Is it a potential bug, or an expected behavior?
