hadoop序列化机制的相关内容

深入对比Java与Hadoop大数据序列化机制Avro

Java有自己提供的序列化机制，而我们的Hadoop也提供了自己的序列化机制，二者究竟有什么差异呢？为什么Hadoop要重新设计自己的序列化体系？序列化大数据对象的过程，Writable接口底层源码实现。首先我们先了解一下什么是序列化，为什么需要序列化？1、序列化机制Serialization序列化...

一脸懵逼学习Hadoop中的序列化机制——流量求和统计MapReduce的程序开发案例——流量求和统计排序

一：序列化概念序列化（Serialization）是指把结构化对象转化为字节流。反序列化（Deserialization）是序列化的逆过程。即把字节流转回结构化对象。Java序列化（java.io.Serializable）二：Hadoop序列化的特点（1）：序列化格式特点：　　紧凑：高效使用...

[Hadoop]序列化机制

传统的计算机系统通过I/O操作与外界进行交流，Hadoop的I/O由传统的I/O系统发展而来，但又有些不同，Hadoop需要处理P、T级别的数据，所以在org.apache.hadoop.io包中包含了一些面向海量数据处理的基本输入输出工具。 1 序列化对象的序列化（Serialization）用...
