Centos6.5下Hbase安装

  1. 下载

http://mirror.bit.edu.cn/apache/hbase/hbase-0.94.26/hbase-0.94.26.tar.gz

2.  解压

tar -zxvf hbase-0.94.26.tar.gz

3. 配置目录

HBASE_HOME/conf/hbase-site.xml

<configuration>
    <property>
    <name>hbase.rootdir</name>
    <value>file:/usr/hbase/hbase-${user.name}</value>
    </property>
</configuration>

4. 配置说明

默认只有<configuration></configuration>配置，没有property配置,需要自己加上
也可以不用配置,直接第四步启动

（hbase默认目录:/tmp/hbase-${user.name},由于很多操作系统会在重启的时候清空/tmp目录,所以这里设置一下比较好）

5. 启动

[[email protected] bin]# ./start-hbase.sh
starting master, logging to /usr/local/hbase-0.94.26/bin/../logs/hbase-root-master-liuchao.out

6. 貌似成功了(试试)

[[email protected] bin]# ./hbase shell
HBase Shell; enter ‘help<RETURN>‘ for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 0.94.26, ra9114543cd48c7e230dabd31f45a086f7b7a5d6a, Wed Dec 17 20:37:01 UTC 2014

hbase(main):001:0> status
1 servers, 0 dead, 2.0000 average load

hbase(main):002:0>

7. 看到这些，说明已经成功了，可以进行下一步测试了

创建一张表

hbase(main):001:0> create ‘testtable‘,‘colfam1‘
0 row(s) in 3.7160 seconds
1:>查看创建的表(写错了)
hbase(main):002:0> list ‘tae‘
TABLE
0 row(s) in 0.2010 seconds

hbase(main):003:0> list ‘testtable‘
TABLE
testtable
1 row(s) in 0.1050 seconds

插入几条数据

hbase(main):004:0> put ‘testtable‘,‘myrow-1‘,‘colfam1:q1‘,‘value-1‘
0 row(s) in 0.4080 seconds

hbase(main):005:0> put ‘testtable‘,‘myrow-2‘,‘colfam1:q2‘,‘value-2‘
0 row(s) in 0.1320 seconds

hbase(main):006:0> put ‘testtable‘,‘myrow-3‘,‘colfam1:q3‘,‘value-3‘
0 row(s) in 0.1090 seconds

查看表中的数据

hbase(main):007:0> scan ‘testtable‘
ROW COLUMN+CELL
myrow-1 column=colfam1:q1, timestamp=1424834391342, value=value-1
myrow-2 column=colfam1:q2, timestamp=1424834424591, value=value-2
myrow-3 column=colfam1:q3, timestamp=1424834464914, value=value-3
3 row(s) in 0.2360 seconds

获取某一行的数据

hbase(main):002:0> get ‘testtable‘,‘myrow-2‘
COLUMN CELL
colfam1:q2 timestamp=1424834424591, value=value-2
1 row(s) in 0.2090 seconds

删除一行数据

hbase(main):003:0> delete ‘testtable‘,‘myrow-2‘,‘colfam1:q2‘
0 row(s) in 0.1110 seconds

hbase(main):004:0> scan ‘testtable‘
ROW COLUMN+CELL
myrow-1 column=colfam1:q1, timestamp=1424834391342, value=value-1
myrow-3 column=colfam1:q3, timestamp=1424834464914, value=value-3
2 row(s) in 0.1780 seconds

禁用并删除表

hbase(main):004:0> disable ‘testtable‘
0 row(s) in 1.4690 seconds
这时再查看，表已经不能用了
hbase(main):005:0> scan ‘testtable‘
ROW COLUMN+CELL

ERROR: org.apache.hadoop.hbase.DoNotRetryIOException: testtable is disabled.

表启用

hbase(main):002:0> enable ‘testtable‘
0 row(s) in 1.5810 seconds
现在又可以用了
hbase(main):002:0> scan ‘testtable‘
ROW COLUMN+CELL
myrow-1 column=colfam1:q1, timestamp=1424834391342, value=value-1
myrow-3 column=colfam1:q3, timestamp=1424834464914, value=value-3
2 row(s) in 0.3160 seconds

删除表

hbase(main):003:0> drop ‘testtable‘

ERROR: Table testtable is enabled. Disable it first.‘

Here is some help for this command:
Drop the named table. Table must first be disabled: e.g. "hbase> drop ‘t1‘"
必须先禁用表，才能删除表
hbase(main):004:0> disable ‘testtable‘
0 row(s) in 1.4460 seconds

hbase(main):005:0> drop ‘testtable‘
0 row(s) in 1.3030 seconds

hbase(main):006:0> scan ‘testtable‘
ROW COLUMN+CELL

ERROR: Unknown table testtable!

退出

hbase(main):001:0> exit

关闭Hbase

[[email protected] bin]# ./stop-hbase.sh
stopping hbase.....................

8. 启动报错

9. 应该是版本不对

之前安装的是hbase-1.0.0-bin.tar.gz 可以版本高了

后来安装的是hbase-0.94.26.tar.gz  没有问题
