HBASE-单节点安装使用简介(UBUNTU 11)
一、环境
机器版本：Ubuntu 11 32bit
hbase版本：hbase-0.90.3
jdk版本：
?????????????? jdk-6u27-linux-i586
?????????????? Linux x86 - Self Extracting Installer
下载地址：http://www.oracle.com/technetwork/java/javase/downloads/index.html
root@dm1:/usr/java# sh ./jdk-6u27-linux-i586.bin
jdk安装后配置，环境变量:
vim /etc/profile
添加
export JAVA_HOME=/usr/java/jdk1.6.0_27
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
二、HBASE 配置
解压 hbase-0.90.3.tar.gz
./conf目录 配置hbase-env.sh 增加:
export JAVA_HOME=/usr/java/jdk1.6.0_27/
?
添加配置存放文件路径:hbase-site.xml (如果没有配置默认存放在/tmp目录下，重启电脑后数据删除)
?
<property>
<name>hbase.rootdir</name>
<value>/usr/hadoop/hbase-0.90.3/data</value>
<description>local dir
</description>
</property>
?
单节点就这样安装好了，下面是启动和简单使用
?
三、使用
HBASE启动进 bin目录
root@dm1:/usr/hadoop/hbase-0.90.3/bin# sh ./start-hbase.sh
HBASE停止 进bin目录
root@dm1:/usr/hadoop/hbase-0.90.3/bin# sh ./stop-hbase.sh
1、登录Hbase shell? 进bin目录
root@dm1:/usr/hadoop/hbase-0.90.3/bin# ./hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 0.90.3, r1100350, Sat May? 7 13:31:12 PDT 2011
hbase(main):001:0>
2、建表
hbase(main):001:0> create 'tb_a','vddb','mw'???
0 row(s) in 2.3740 seconds
hbase(main):002:0>
3、插入vddb 列 2个数据 begin_dt & end_dt? 没法一次put 一行的多个字段
hbase(main):007:0* put 'tb_a','task001','vddb:begin_dt','2011-10-12 18:00:00'??????????????????????????????????
0 row(s) in 0.2320 seconds
hbase(main):010:0* put 'tb_a','task001','vddb:end_dt','2011-10-12 18:00:10'????????????????????????????????????
0 row(s) in 0.0480 seconds
4、查询
hbase(main):012:0* scan 'tb_a'
ROW?????????????????????????????????????????? COLUMN+CELL??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
task001????????????????????????????????????? column=vddb:begin_dt, timestamp=1318416290895, value=2011-10-12 18:00:00?????????????????????????????????????????????????????????
task001????????????????????????????????????? column=vddb:end_dt, timestamp=1318416304997, value=2011-10-12 18:00:10???????????????????????????????????????????????????????????
1 row(s) in 0.1820 seconds
? hbase(main):013:0> get 'tb_a','task001'
COLUMN??????????????????????????????????????? CELL?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
vddb:begin_dt??????????????????????????????? timestamp=1318416290895, value=2011-10-12 18:00:00???????????????????????????????????????????????????????????????????????????????
vddb:end_dt????????????????????????????????? timestamp=1318416304997, value=2011-10-12 18:00:10???????????????????????????????????????????????????????????????????????????????
2 row(s) in 0.0760 seconds
查询条件过滤
scan 'traceLogTask',{column=>['uuid'],LIMIT=>2,STARTROW=>'2011101710010002'}
?
scan 'traceLogTask',{COLUMN=>['uuid','VDDB:'],STARTROW=>'2011101710010002',STOPROW=>'2011101710010004'}
?
