intbyteSize=Integer.BYTES; 1. 这行代码将会返回整数类型的字节大小,并将其赋值给byteSize变量。 步骤4: 输出整数类型的字节大小 最后,我们可以使用以下代码来输出整数类型的字节大小: System.out.println("The byte size of integer in Java is: "+byteSize); 1. 这行代码会在控制台上输出整数类型的字节大小。

分片大小需要您通过odps.stage.mapper.split.size参数进行配置。分片逻辑请参见MapReduce流程说明。 计算平均值第一阶段:每个Worker统计分片内数据的个数及汇总值。您可以将每个分片内的数据个数及汇总值视为一个中间结果。 计算平均值第二阶段:汇总第一阶段中每个分片内的信息。
