1.2. Quick Start
Loopback IP
/etc/hosts should look something like this:
- vi /etc/hosts
- 127.0.0.1 localhost
- 127.0.0.1 ubuntu.ubuntu-domain ubuntu
1.2.1. Download and unpack the latest stable release.（下载和解压稳定版本）
- $ tar xfvz hbase-0.94.3-security.tar.gz
- $ cd hbase-0.94.3-security
安装之前，编辑 conf/hbase-site.xml.其中hbase.rootdir，是Hbase写数据的目录
其中hbase.zookeeper.property.dataDir，是ZooKeeper写数据的目录
- <?xml version="1.0"?>
- <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
-
-
- hbase.rootdir
- /data/hbase
-
-
- hbase.zookeeper.property.dataDir
- /data/zookeeper
-
-
1.2.2. Start HBase
- [root@ZSDDB8 hbase-0.94.3-security]# ./bin/start-hbase.sh
- starting master, logging to /root/hbase-0.94.3-security/bin/../logs/hbase-root-master-ZSDDB8.out
这样就算开启了单实例的HBase
Is java Installed?可以查看http://blog.chinaunix.net/space.php?uid=26446098&do=blog&id=3438622 java7安装方式
1.2.3. Shell Exercises
通过shell连接HBASE
- [root@ZSDDB8 hbase-0.94.3-security]# ./bin/hbase shell
- HBase Shell; enter 'help' for list of supported commands.
- Type "exit" to leave the HBase Shell
- Version 0.94.3, r1408904, Wed Nov 14 16:41:36 UTC 2012
- hbase(main):001:0>
创建一个表为test且一个列集合为cf。通过list 'test'验证它的创建然后插入一些数据
- hbase(main):003:0> create 'test', 'cf'
- 0 row(s) in 1.2200 seconds
- hbase(main):002:0> list 'test'
- TABLE
- test
- 1 row(s) in 0.0170 seconds
- 1 row(s) in 0.0550 seconds
- hbase(main):004:0> put 'test', 'row1', 'cf:a', 'value1'
- 0 row(s) in 0.0560 seconds
- hbase(main):005:0> put 'test', 'row2', 'cf:b', 'value2'
- 0 row(s) in 0.0370 seconds
- hbase(main):006:0> put 'test', 'row3', 'cf:c', 'value3'
- 0 row(s) in 0.0450 seconds
通过执行scan 命令验证刚插入的数据
- hbase(main):006:0> scan 'test'
- ROW COLUMN+CELL
- row1 column=cf:a, timestamp=1355386368983, value=value1
- row2 column=cf:b, timestamp=1355386374028, value=value2
- row3 column=cf:c, timestamp=1355386377745, value=value3
- 3 row(s) in 0.0600 seconds
得到一行的数据
- hbase(main):007:0> get 'test', 'row1'
- COLUMN CELL
- cf:a timestamp=1355386368983, value=value1
- 1 row(s) in 0.0330 seconds
现在disable然后drop掉你的表，就可以清除上面你做的所有操作
- hbase(main):008:0> disable 'test'
- 0 row(s) in 2.0730 seconds
- hbase(main):009:0> drop 'test'
- 0 row(s) in 0.1100 seconds
退出
1.2.4. Stopping HBase
执行stop-hbase.sh关闭HBase
- $ ./bin/stop-hbase.sh
- [root@ZSDDB8 hbase-0.94.3-security]# ./bin/stop-hbase.sh
- stopping hbase...........
1.2.5. Where to go next
The above described standalone setup is good for testing and experiments only. In the next chapter,
Chapter 2, Apache HBase (TM) Configuration, we'll go into depth on the different HBase run modes, system requirements running HBase, and critical configurations setting up a distributed HBase deploy.
