Question

我有两台笔记本电脑。它们都安装了windows7（64位），JDK 1.8.0_144（64位）和Ignite 2.1.0。我在第一个笔记本的WindowsCMD中使用简单的配置xml启动了一个点亮节点，就像官方示例一样，然后我运行我的代码来启动点火节点，在另一个笔记本上添加Eclipse中的大量数据。以下是我的代码的一些关键部分：

IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setPeerClassLoadingEnabled(true);
TcpDiscoverySpi tcpDiscoverySpi = new TcpDiscoverySpi();
tcpDiscoverySpi.setAckTimeout(15000);
tcpDiscoverySpi.setNetworkTimeout(60000);
TcpDiscoveryMulticastIpFinder ipFinder = new TcpDiscoveryMulticastIpFinder();
ipFinder.setAddresses(Arrays.asList("127.0.0.1:47500..47509","192.168.1.105:47500..47509")); //two addresses of the notebook computers
tcpDiscoverySpi.setIpFinder(ipFinder);
cfg.setDiscoverySpi(tcpDiscoverySpi);
Ignite ignite = Ignition.start(cfg); //start ignite node
CacheConfiguration<Long, Map> cacheConf = new CacheConfiguration();
cacheConf.setName(CACHE_NAME).setCacheMode(CacheMode.PARTITIONED);
cacheConf.setBackups(0);
IgniteCache cache = ignite.getOrCreateCache(cacheConf); //create cache

IgniteDataStreamer<Long,Map> ds = ignite.dataStreamer(CACHE_NAME);
ds.autoFlushFrequency(10000);
ds.perNodeBufferSize(1024);
ds.perNodeParallelOperations(8);
……  //some code to prepare for reading text data from local file
while((line=br.readLine())!=null){ // br is a BufferedReader instance
    ds.addData(count++, parseData(line, Constants.DEFAULT_SEPARATOR, fields)); //parseData method return a Map instance
    if(count%100000==0){
        System.out.println(count+" loaded...");
    }
}
…… //other code

在多次调用ds.addData之前运行没有错误，并发生以下异常：

是什么原因？我该怎么做才能解决问题？
