本篇博客主要介绍 hbase 的安装，以及利用 ycsb 对 hbase 进行基本的测试

步骤一：
在http://mirrors.hust.edu.cn/apache/hbase/下载hbase稳定版：
hbase-0.94.14.tar.gz 存放于 /home/hs/program 目录下
cd /home/hs/program
tar -zxvf hbase-0.94.14.tar.gz


步骤二：
修改/home/hs/program/YCSB/hbase目录下的pom.xml文件（根据你所使用的hbase版本和hadoop版本，注意红色部分）：


4.0.0

com.yahoo.ycsb
root
0.1.4

hbase-binding
HBase DB Binding


org.apache.hbase
hbase

0.94.14


org.apache.hadoop
hadoop-core

1.0.4


com.yahoo.ycsb
core
${project.version}







org.apache.maven.plugins
maven-assembly-plugin
${maven.assembly.version}


jar-with-dependencies

false



package

single











步骤三：
因为更改了步骤二中的文件，所以需要重新编译YCSB项目
cd /home/hs/program/YCSB
mvn clean package | tee mvn-clean-package.dat //将输出同时输出到屏幕和文件
显示与下类似信息，则说明编译成功：

步骤四：
成功编译YCSB之后，在/home/hs/program/YCSB/distribution/target目录下会有ycsb-0.1.4.tar.gz
将该文件解压到/home/hs/program目录下：
tar -zxvf /home/hs/program/YCSB/distribution/target -C /home/hs/program

步骤五：
将/home/hs/program/hbase-0.94.14/lib中的以下文件：
slf4j-api-*.jar
slf4j-log4j12-*.jar
zookeeper-*.jar
拷贝到/home/hs/program/ycsb-0.1.4/hbase-binding/lib中

步骤六：
使用/home/hs/program/hbase-0.94.14/conf中的hbase-site.xml
替换掉/home/hs/program/ycsb-0.1.4/hbase-binding/conf中的hbase-site.xml

步骤七：
执行测试
终端1：
进入hbase的安装目录：
执行：./bin/start-hbase.sh
显示：
starting master, logging to /home/hs/program/hbase-0.94.14/bin/../logs/hbase-hs-master-hs-virtual-machine.out

接着执行：
./bin/hbase shell
create 'usertable','cf'

终端2中：
cd /home/hs/program/ycsb-0.1.4

hs@hs-virtual-machine:~/program/ycsb-0.1.4$ ./bin/ycsb load hbase -P workloads/workloada -p hosts=localhost -p columnfamily=cf > ./my-results/load-hbase-a

hs@hs-virtual-machine:~/program/ycsb-0.1.4$ ./bin/ycsb run hbase -P workloads/workloada -p hosts=localhost -p columnfamily=cf > ./my-results/run-hbase-a

得到如下结果：
YCSB Client 0.1
Command line: -db com.yahoo.ycsb.db.HBaseClient -P workloads/workloada -p hosts=localhost -p columnfamily=cf -t
