HBase Shell基本操作

首先启动hadoop集群与hbase服务
start-all.sh
hbase-1.1.3/bin/start-hbase.sh
接下来使用hbase shell命令来连接正在运行的Hbase实例，该命令位于HBase安装包下的bin/目录
hbase-1.1.3/bin/hbase shell

SHELL USAGE:
Quote all names in HBase Shell such as table and column names. 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', "keyx03x3fxcd"
hbase> get 't1', "key032311"
hbase> put 't1', "testxefxff", 'f1:', "x01x33x40"

The HBase shell is the (J)Ruby IRB with the above HBase-specific commands added.

查看有哪些表
list

退出HBase Shell
quit

数据定义（DDL）操作：

使用create命令来创建一个新的表。在创建的时候，必须指定表名（test）和列族名（cf）。
create 'test', 'cf'

列举表信息
list 'test'

获取表描述
describe 'test'

检查表是否存在
exists 'test'

清空表数据
truncate 'test'

禁用一个表
disable 'test'
重新启用表
enable 'test'

删除表。删除表之前，需要先disable表
drop 'test'

数据管理（DML）操作：

使用put命令，将数据插入表中
put 'test', 'row1', 'cf:a', 'value1'
put 'test', 'row2', 'cf:a', 'value2'
put 'test', 'row3', 'cf:a', 'value3'

一次性扫描全表数据
scan 'test'
获取一行数据
get 'test', 'row1'

删除数据：
删除一个单元格，必须指定列名
delete '<table name>', '<row>', ‘<family:column>’,‘<time stamp>’
删除一行
deleteall '<table name>', '<row>'
