环境:
操作系统:ubuntu 12.10 64bit
jdk:sun jdk 1.6 64bit
hadoop:apache hadoop 1.02
hbase：apache hbase 0.92
先决条件:配置apache hadoop append,默认这个属性是false，需要设置为true
1）下载hbase
解压到每台服务器的/data/soft
解压
root@master:/data/soft# tar zxvf hbase-0.92.0.tar.gz
建立软连
root@master:/data/soft ln -s hbase-0.92.0 hbase
2）配置hbase
前提是安装完成hadoop，默认在namenode上进行
1.修改conf/hbase-env.sh，添加jdk支持
export JAVA_HOME=/usr/local/jdk export HBASE_MANAGES_ZK=true export HBASE_LOG_DIR=/data/logs/hbase
2. 修改conf/hbase-site.xml，
<property> name>hbase.rootdir</value>hdfs://master:9000/hbase>hbase.cluster.distributed>true>hbase.master>hdfs://master:60000> >hbase.zookeeper.quorum>slave-001,slave-002,slave-003description>Comma separated list of servers in the ZooKeeper Quorum. For example,"host1.mydomain.com,host2.mydomain.com,host3.mydomain.com". By default this is set to localhost for local and pseudo-distributed modes of operation. For a fully-distributed setup,this should be set to a full list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is set in hbase-env.sh this is the list of servers which we will start/stop ZooKeeper on. >hbase.zookeeper.property.dataDir>/data/work/zookeeper>Property from ZooKeeper's config zoo.cfg. The directory where the snapshot is stored. >
hbase.rootdir设置hbase在hdfs上的目录，主机名为hdfs的namenode节点所在的主机
hbase.cluster.distributed设置为true，表明是完全分布式的hbase集群
hbase.master设置hbase的master主机名和端口
hbase.zookeeper.quorum设置zookeeper的主机，建议使用单数
3.修改hadoop的目录下的conf/hdfs-site.xml
>dfs.datanode.max.xcievers>4096>
4.修改conf/regionservers
将所有的datanode添加到这个文件，类似与hadoop中slaves文件
5.拷贝hbase到所有的节点
6. 启动hbase
$ ./bin/start-hbase.sh
7 hbase自带的web界面
http://master:60010/
8 测试
1).登录hbase客户端
./bin/hbase shell
2).新建数据表，并插入3条记录
hbase(main):003:0> create 'test','cf' 0 row(s) in 1.2200 seconds hbase(main):003:0> list 'table' test 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>in 0.0370 seconds hbase(main):006:0>in 0.0450 seconds
3).查看插入的数据
hbase(main):007:0> scan 'test' ROW COLUMN+CELL row1 column=cf:a,timestamp=1288380727188,value=value1 row2 column=cf:b,timestamp=1288380738440,0)">value2 row3 column=cf:c,timestamp=1288380747365,0)">value3 3 row(s) in 0.0590 seconds
4).读取单条记录
hbase(main):008:0> get 'test','row1' COLUMN CELL cf:a timestamp=1288380727188,0)">value1 1 row(s) in 0.0400 seconds
5).停用并删除数据表
hbase(main):012:0> disable 'test' 0 row(s) in 1.0930 seconds hbase(main):013:0> drop 'test' 0 row(s) in 0.0770 seconds
6).退出
hbase(main):014:0> exit
