hadoop学习第四天-Writable和WritableComparable序列化接口的使用&&MapReduce中传递javaBean的简单例子

1.如果一个javaBean想要作为MapReduce的key或者value,就一定要实现序列化,因为在Map到Reduce阶段的时候,只能是传输二进制数据,不可能将字符流直接进行RPC传输,只要一个javabean实现了序列化和反序列化,就可以做为key或者value最简单的序列化和反序列化就是实现Writable接...

Ansible:遇到错误 "sudo: /etc/sudoers is world writable sudo: no valid sudoers sources found, quitting

执行ansible-playbook时,遇到该错误:经过检查发现是因为在Linux中/etc/sudoers该文件必须是只读权限的才行,故我们需要修改其权限为440,到root账户下修改,直接chmod0440/etc/sudoers就可以了。 转自:https://blog.csdn.net/wzh7019...

Hadoop WritableComparable接口

WritableComparable接口Writable接口大家可能都知道,它是一个实现了序列化协议的序列化对象。在Hadoop中定义一个结构化对象都要实现Writable接口,使得该结构化对象可以序列化为字节流,字节流也可以反序列化为结构化对象。那WritableComparable接口是可序列化并且可比较的接口。M...
