环境
虚拟机：VMware 10
Linux版本：CentOS-6.5-x86_64
客户端：Xshell4
FTP：Xftp4
jdk8
hadoop-3.1.1
hbase-2.1.3
一、本地模式搭建
1、解压HBase，配置HBase环境变量
[root@PCS102 local]# tar -zxvf hbase-2.1.3-bin.tar.gz -C /usr/local/
[root@PCS102 local]# vi /etc/profile
[root@PCS102 local]# source /etc/profile
2、hbase-env.sh中配置JAVA_HOME
export JAVA_HOME=/usr/local/jdk1.8.0_65
3、配置hbase-site.xml
<configuration> <property> <name>hbase.rootdir</name> <value>file:///home/testuser/hbase</value> </property> <property> <name>hbase.zookeeper.property.dataDir</name> <value>/home/testuser/zookeeper</value> </property> <property> <name>hbase.unsafe.stream.capability.enforce</name> <value>false</value> </property> </configuration>
4、启动
[root@PCS102 bin]# /usr/local/hbase-2.1.3/bin/start-hbase.sh [root@PCS102 bin]# jps 20437 Jps 20055 HMaster
#进入控制台 HBASE SHELL 表的相关操作

Commas delimit command parameters. Type <RETURN> after entering a command to run it. Dictionaries of configuration used in the creation and alteration of tables are Ruby Hashes. They look like this: {'key1' => 'value1', 'key2' => 'value2', ...} and are opened and closed with curley-braces. Key/values are delimited by the '=>' character combination. Usually keys are predefined constants such as NAME, VERSIONS, COMPRESSION, etc. Constants do not need to be quoted. Type 'Object.constants' to see a (messy) list of all constants in the environment. If you are using binary keys or values and need to enter them in the shell, use double-quote'd hexadecimal representation. For example: hbase> get 't1', "key\x03\x3f\xcd" hbase> get 't1', "key\003\023\011" hbase> put 't1', "test\xef\xff", 'f1:', "\x01\x33\x40" The HBase shell is the (J)Ruby IRB with the above HBase-specific commands added.

注意：hbase-env.sh配置：HBASE_MANAGERS_ZK=true 默认值true
HBase伪分布式默认使用内置zookeeper
二、伪分布式搭建
三、完全分布式搭建
