Apache Ignite - NPE, когда клиент dotnet пытается создать кеш на сервере

0 голосов
/ 03 сентября 2018

Я пытаюсь выполнить настройку с помощью Apache Ignite. У меня есть клиентское приложение ядра dotnet, которое пытается либо получить кеш (ignite.GetCache<int, CacheThing>("test-cache")), либо создать кеш (ignite.CreateCache<int, CacheThing>).

В обоих случаях результатом является одна и та же ошибка (см. Ниже).

Apache Ignite Server

Я использую Docker-контейнер из https://hub.docker.com/r/apacheignite/ignite/, и использую тег apache/ignite:2.6.0.

Код клиента (dotnetcore)

Клиент пытается создать кэш, используя пользовательскую сборку ядра dotnet для определения схемы. 

class Program
    {
        public static bool ClientDisconnected = false;

        static void Main(string[] args)
        {
            Console.WriteLine("Starting client");
            string x = typeof(CacheStoreFactory).FullName;
            Console.WriteLine("Cache factory: " + x);
            var cfg = new IgniteConfiguration
            {
                SpringConfigUrl = "ignite.config",
                JvmOptions = new[]
                {
                    "-Xdebug","-DIGNITE_QUIET=false"
                },
            };

            /*
            var cfg = new IgniteConfiguration()
            {
                ClientMode = true,
                JvmOptions = new[]
                {
                    "-Xdebug","-DIGNITE_QUIET=false"
                },
                BinaryConfiguration = new BinaryConfiguration
                {
                    Types = new List<string>
                    {
                        typeof(CacheStoreFactory).FullName,
                    }
                },
            };
             */


            Console.WriteLine("Ignite -> Start");
            using (IIgnite ignite = Ignition.Start(cfg))
            {
                Console.WriteLine("Destroy test-cache");


                //ignite.DestroyCache("test-cache");
                //ICache<int, CacheThing> cache = ignite.GetCache<int, CacheThing>("test-cache");


                ICache<int, CacheThing> cache = ignite.CreateCache<int, CacheThing>(new CacheConfiguration
                {
                    Name = "test-cache",
                    ReadThrough = true,
                    WriteThrough = true,
                    KeepBinaryInStore = true,
                    CacheStoreFactory = new CacheStoreFactory()
                });





                ignite.ClientDisconnected += (sender, eventArgs) =>
                {
                    ClientDisconnected = true;

                    Console.WriteLine("Client disconnected.");
                };

                ignite.ClientReconnected += (sender, eventArgs) =>
                {
                    ClientDisconnected = false;

                    Console.WriteLine("Client reconnected.");
                };

                Object retrieved = cache.Get(1);

                Console.WriteLine(retrieved);

                Console.WriteLine("Press enter to quit client");
                Console.ReadLine();
            }
        }
    }

Возможно ли даже для клиента dotnet создать кеш на Java-сервере Apache Ignite?

.NET Cache Store не может быть развернут на узле только Java .

Контейнер Docker содержит Ignite только для Java, и вы создаете собственное Cache Store в своем коде C #.

Таким образом, если команда Ignite не выпустит образ Docker под управлением Ignite.NET, вам придется создать собственный образ Docker или запустить серверные узлы Ignite.NET другим способом.
