Ignition.Start() is not picking the default config from {IGNITEHOME}/config/default-config.xml and error on starting the server with config file name

Two strange issues when using Apache Ignite.NET

  1. Ignition.Start() method is not picking the default config file path from {IGNITEHOME}/config/default-config.xml instead using all system defaults.

  2. Getting an error while specifying the default config file path but server start successfully without config file path (Ignition.Start()).

Below is the simple code, logg and config file.

static void Main(string[] args)
{

    Console.WriteLine("IGNITE_HOME=" + Environment.GetEnvironmentVariable("IGNITE_HOME"));


     var ignite = Ignition.Start(@"C:/Apache/gridgain-community-8.8.16/config/default-config.xml");
    //var ignite = Ignition.Start();
    var cache = ignite.GetOrCreateCache<int, string>("my-cache");
    cache.Put(1, "Hello, World");
    Console.WriteLine(cache.Get(1));
}

The main error

Solution

  • Invalid header on deserialization is caused by a mismatch between .NET and Java parts of Apache Ignite.

    1. Do a clean rebuild (delete bin and obj directories from your project). Old jar files get stuck there sometimes when switching from Ignite to GridGain and/or between different versions of Ignite/GridGain.

    2. IGNITE_HOME environment variable is NOT needed when using Ignite.NET from NuGet, remove it from the system. It is needed only for custom deployments. See https://ignite.apache.org/docs/latest/net-specific/net-deployment-options#custom-deployment
