半夜醒来：会不会是因为我缓存是在任务外声明的，所以执行任务是引用都是同一台机器上的缓存

// Inject Ignite instance.
    @IgniteInstanceResource
    private Ignite ignite;
IgniteCache certSrcCache =  ignite.cache("cert_src");//******这里声明
    @Override
    public List<ComputeJob> split(int gridSize, CreditCalculate arg) {
        
        List<ComputeJob> jobs = new ArrayList<>();

        SqlQuery sql2 = new SqlQuery(CertSrc.class, "from ...");
        QueryCursor<Cache.Entry<Long, CertSrc>> companyList = certSrcCache.query(sql2);
       ...

        for (Cache.Entry<Long, CertSrc> e : companyList) {

######回复 @fir01 : 如果默认的端口被占用的话，会使用一个随机的端口，我估计你看看节点启动时的控制台输出应该会有的。######回复 @fir01 : 任务数没有数量限制，这个看你的内存配置了。######回复 @李玉珏 : 端口好像是随机的，怎么从本机访问远程机器的h2控制台，或者在哪里配置固定的端口呢？######回复 @李玉珏 : 谢谢回复。好像是搞定了，估计mapReduce有bug或者要配置，在ubuntu里面就是单线程的,windows是多线程。换executorService就都可以异步多线程了，但是ubuntu里面执行看打印还是会执行一会就停个6秒，为什么呢？是不是存放任务的队列有大小限制？任务总数10823######回复 @fir01 : SHARED是默认的部署模式。###### 我想我还要测试一下是不是我本机发送任务速度慢。7519个任务1秒钟就发送完毕。######任务数不要太多，你可以换一个维度，控制下任务的总数量，大量的任务处于排队状态，是很占用资源的。######都是用ignite自己的broadcast方法异步发布任务就又快又流畅，无卡顿现象。看样子非官方的，说可以用的东西最好别用。
