此默认实例使用名称 services/cache/distributedmap 绑定到全局 Java 命名和目录接口 (JNDI) 命名空间。 多个实例DistributedMap和DistributedObjectCache同一 Java 虚拟机 (JVM) 上的接口使应用程序可以根据需要单独配置缓存实例。 DistributedMap 接口的每个实例都有自己的属性。 提示:有关DistributedMap和DistributedObjectCa...

1.1.1 map端连接- DistributedCache分布式缓存小数据集 当一个数据集非常小时,可以将小数据集发送到每个节点,节点缓存到内存中,这个数据集称为边数据。用map函数将小数据集中的数据按键聚合到大的数据集中,输出连接数据集,进行连接操作。 (1) 分布式缓存指定缓存文件

2、在自己的mapper类中,使用distributedCache的接口获取文件下载到本地后的路径 这里查了些网上的使用示例,大部分例子在mapper类中重写configure接口(或者setup),将本地文件的路径保存在mapper类的成员变量中,供下面的map成员函数使用。 在myMapper类的configure中获取文件的路径: ...
