前提:已经安装hadoop(本文版本1.0.1)
1.
解压hbase包,无需安装
tar xfz hbase-0.94.0.tar.gz
2.
在conf/hbase-site.xml,设置存储位置,可以是hdfs,也可以是本地文件系统
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:9000/hbase</value>
<!-- <value>file:///home/hbase</value> -->
</property>
</configuration>
3.
为了方便,导入环境变量
export HBASE_HOME=/usr/hbase-0.94.0
export PATH=$PATH:$HBASE_HOME/bin
4.
消除slf4j的包冲突
mv slf4j-api-1.5.8.jar slf4j-api-1.5.8.jar.bak
mv slf4j-log4j12-1.5.8.jar slf4j-log4j12-1.5.8.jar.bak
5.
启动hbase
start-hbase.sh
必须先启动hadoop-dfs ,版本1.0.1
日志:/安装目录/logs
6.
通过命令行链接hbase
hbase shell
7.
帮助命令 help
提示:
HBase Shell, version 0.94.0, r1332822, Tue May 1 21:43:54 UTC 2012
Type 'help "COMMAND"', (e.g. 'help "get"' -- the quotes are necessary) for help on a specific command.
Commands are grouped. Type 'help "COMMAND_GROUP"', (e.g. 'help "general"') for help on a command group.
COMMAND GROUPS:
Group name: general
Commands: status, version
Group name: ddl
Commands: alter, alter_async, alter_status, create, describe, disable, disable_all, drop, drop_all, enable, enable_all, exists, is_disabled, is_enabled, list, show_filters
Group name: dml
Commands: count, delete, deleteall, get, get_counter, incr, put, scan, truncate
Group name: tools
Commands: assign, balance_switch, balancer, close_region, compact, flush, hlog_roll, major_compact, move, split, unassign, zk_dump
Group name: replication
Commands: add_peer, disable_peer, enable_peer, list_peers, remove_peer, start_replication, stop_replication
Group name: security
Commands: grant, revoke, user_permission
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', "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.
For more on the HBase Shell, see http://hbase.apache.org/docs/current/book.html
例如:help "create"
8.
创建名为test的表,表有一个列族cf。
create 'test', 'cf'
put 'test', 'row1', 'cf:a', 'value1'
put 'test', 'row2', 'cf:b', 'value2'
put 'test', 'row3', 'cf:c', 'value3'
查询表
scan 'test'
获取单独的一行
get 'test', 'row1'
禁用和删除 表
disable 'test'
drop 'test'
9.
退出命令行
exit
