Hbase配置手册
1）下载hbase
解压到每台服务器的/data/soft
解压
- root@master:/data/soft# tar zxvf hbase-0.90.0.tar.gz
root@master:/data/soft# tar zxvf hbase-0.90.0.tar.gz
建立软连
- root@master:/data/soft# ln -s hbase-0.90.0 hbase
root@master:/data/soft# ln -s hbase-0.90.0 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
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</name>
- <value>hdfs://master:9000/hbase</value>
- </property>
- <property>
- <name>hbase.cluster.distributed</name>
- <value>true</value>
- </property>
- <property>
- <name>hbase.master</name>
- <value>hdfs://master:60000</value>
- </property>
-
- <property>
- <name>hbase.zookeeper.quorum</name>
- <value>slave-001,slave-002,slave-003</value>
- <description>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. </description>
- </property>
- <property>
- <name>hbase.zookeeper.property.dataDir</name>
- <value>/data/work/zookeeper</value>
- <description>Property from ZooKeeper's config zoo.cfg. The directory where the snapshot is stored. </description>
- </property>
<property>
<name>hbase.rootdir</name>
<value>hdfs://master:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.master</name>
<value>hdfs://master:60000</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>slave-001,slave-002,slave-003</value>
<description>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. </description>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/data/work/zookeeper</value>
<description>Property from ZooKeeper's config zoo.cfg. The directory where the snapshot is stored. </description>
</property>
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
- <property>
- <name>dfs.datanode.max.xcievers</name>
- <value>4096</value>
- </property>
<property>
<name>dfs.datanode.max.xcievers</name>
<value>4096</value>
</property>
4.复制hadoop的jar到hbase的lib目录下，删除原来的lib下的hadoop.jar
原来的hadoop-core-0.20-append-r1056497.jar
新的hadoop-0.20.2-core.jar
5.修改conf/regionservers
将所有的datanode添加到这个文件，类似与hadoop中slaves文件
6.拷贝hbase到所有的节点
3）启动hbase
- $Snbsp;./bin/start-hbase.sh
$ ./bin/start-hbase.sh
4）hbase自带的web界面
http://master:60010/
5）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> 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
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> 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
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, value=value2
- row3 column=cf:c, timestamp=1288380747365, value=value3
- 3 row(s) in 0.0590 seconds
hbase(main):007:0> scan 'test'
ROW COLUMN+CELL
row1 column=cf:a, timestamp=1288380727188, value=value1
row2 column=cf:b, timestamp=1288380738440, value=value2
row3 column=cf:c, timestamp=1288380747365, value=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, value=value1
- 1 row(s) in 0.0400 seconds
hbase(main):008:0> get 'test', 'row1'
COLUMN CELL
cf:a timestamp=1288380727188, value=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
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
