如果测试数据缺少这些输入列，则会出现错误。解决方案：1.检查训练数据包含哪些列，确保测试数据也有相同的列（除了标签列可能不是必需的，但特征列必须存在且结构相同）。2.确保测试数据与训练数据的列名一致。例如...

Map端会处理输入数据并产生中间结果,这个中间结果会写到本地磁盘,每个Map的输出会先写到内存缓冲区中,当写入的数据达到设定的阈值时,系统将会启动一个线程将缓冲区的数据写到磁盘,这个过程叫做spill(spill写入之前,会先进行二次排序,首先根据数据所属的partition进行排序,然后每个partition中的数据再按key来排序 . partition的目是将记录划分到不同的Reducer上去,以期望能够达到负载均衡,以后的Reducer就会根据partition来读取自己对应的数据 . 接着运行co
