Apache Igniteキャッシュの作成中にエラーが発生しました

Question

キャッシュを作成しようとしています（実際にどのように動作するかを理解するためにサンプルコードからほぼコピーして貼り付けています）。私はのIgniteノードを開始することができるよしかしときにはキャッシュを作成しようとする時にスタックトレースを次のようにエラーを取得：

コードは次のとおりです。

import org.apache.ignite.Ignite; 
import org.apache.ignite.IgniteCache; 
import org.apache.ignite.IgniteException; 
import org.apache.ignite.Ignition; 
import org.apache.ignite.cache.CacheAtomicityMode; 
import org.apache.ignite.configuration.CacheConfiguration; 
import org.apache.ignite.spi.indexing.IndexingQueryFilter; 

/**

*/ 
public class CacheApiExample { 
    public static void main(String[] args) throws IgniteException { 
     Ignition.setClientMode(true); 

     try(Ignite ignite = Ignition.start("examples/config/example-ignite.xml")) { 
      CacheConfiguration<Integer, String> cfg = new CacheConfiguration<>(); 
      cfg.setName("Democache"); 
      cfg.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL); 

      IgniteCache<Integer, String> cache = ignite.getOrCreateCache(cfg); 

      cache.put(1, "cache item 1"); 
      cache.put(2, "cache item 2"); 

      System.out.println(cache.get(1)); 
      System.out.println(cache.get(2)); 
     } 
    } 
}

$ IGNITE_HOMEていることを確認してください/ libs/ignite-indexing/*はクラスパスにあります。

またはH2への依存が含まれている必要があり、あなたのプロジェクト：

<dependency> 
    <groupId>com.h2database</groupId> 
    <artifactId>h2</artifactId> 
    <version>1.3.175</version> 
</dependency>
