一.环境配置 由于集群至少需要三台服务器,我就拿上次做的MongoDB Master, Slave, Arbiter环境来做Hadoop集群.服务器还是ibmcloud 免费提供的.其中Arbiter在这里做的也是slave的角色. Hostname IP  Server Type Master 192.168.0.28 Centos6.2 Slave 192.168.0.29 Ubuntu14.04 Arbiter 192.168.0.30 Ubuntu14.04 配置三台机器的Master

Mac下安装HBase及详解 1. 千篇一律的HBase简介 HBase是Hadoop的数据库, 而Hive数据库的管理工具, HBase具有分布式, 可扩展及面向列存储的特点(基于谷歌BigTable). HBase可以使用本地文件系统和HDFS文件存储系统, 存储的是松散的数据(key-value的映射关系). HBase位于HDFS的上层, 向下提供存储, 向上提供运算 2. HBase安装 HBase有单机, 伪分布式, 全分布式运行模式 依赖: 匹配HBase的Hadoop版本 Jav
