使用Python连接Hbase数据库
1，Hbase下载。
下载地址：http://hbase.apache.org/downloads.html
2，本地Hbase安装
root@master:/usr/local/setup_tools# tar -zxvf hbase-2.0.0-bin.tar.gz
root@master:/usr/local/setup_tools# mv hbase-2.0.0 /usr/local/
root@master:/usr/local/setup_tools# cd /usr/local
root@master:/usr/local# ls | grep hbase
hbase-2.0.0
root@master:/usr/local#
root@master:/usr/local/hbase-2.0.0# vi /etc/profile
export HBASE_HOME=/usr/local/hbase-2.0.0
export PATH=.:$PATH:$JAVA_HOME/bin:$SCALA_HOME/bin:$HADOOP_HOME/bin:$SPARK_HOME/bin:$HIVE_HOME/bin:$FLUME_HOME/bin:$ZOOKEEPER_HOME/bin:$KAFKA_HOME/bin:$IDEA_HOME/bin:$eclipse_HOME:$MAVEN_HOME/bin:$ALLUXIO_HOME/bin:$HBASE_HOME/bin
root@master:/usr/local/hbase-2.0.0# source /etc/profile
3，配置
修改hbase-site.xml，设置存储数据的根目录。
root@master:/usr/local/hbase-2.0.0/conf# vi hbase-site.xml
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///usr/local/hbase-2.0.0/data</value>
</property>
</configuration>
4，启动hbase
root@master:/usr/local/hbase-2.0.0# cd bin
root@master:/usr/local/hbase-2.0.0/bin# ls
considerAsDead.sh hbase hbase-config.cmd hbase-jruby master-backup.sh replication start-hbase.sh zookeepers.sh
draining_servers.rb hbase-cleanup.sh hbase-config.sh hirb.rb region_mover.rb rolling-restart.sh stop-hbase.cmd
get-active-master.rb hbase.cmd hbase-daemon.sh local-master-backup.sh regionservers.sh shutdown_regionserver.rb stop-hbase.sh
graceful_stop.sh hbase-common.sh hbase-daemons.sh local-regionservers.sh region_status.rb start-hbase.cmd test
root@master:/usr/local/hbase-2.0.0/bin# start-hbase.sh

二，使用Python连接Hbase。
1，建立Python开发环境 ---虚拟环境。
先进行检查。
root@master:/usr/local/hbase-2.0.0/bin# pip
The program 'pip' is currently not installed. You can install it by typing:
apt-get install python-pip
root@master:/usr/local/hbase-2.0.0/bin# python
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
root@master:/usr/local/hbase-2.0.0/bin#
安装pip。
root@master:/usr/local/hbase-2.0.0/bin# apt-get install python-pip
