1 安装HBase，有条件的同学都按完全分布式安装，将安装过程和最后测试成功的界面抓图提交

1、去apache下载hbase-0.94.16.tar.gz

2、解压缩到

[hadoop@hadoop4 ~]$ tar zxvf hbase-0.94.16.tar.gz

3、[hadoop@hadoop4 conf]$ vihbase-site.xml

4、配置regionservers

[hadoop@hadoop4 conf]$ vi regionservers

hadoop5

hadoop6

5、配置vi /etc/profile

exportHBASE_HOME=/home/hadoop/hbase-0.94.16

exportPATH=$HBASE_HOME/bin:/opt/mysql5168/bin:$JAVA_HOME/bin:$HADOOP_HOME/bin:$PATH:$HIVE_HOME/bin:/home/hadoop/pig-0.12.0/bin:$MAHOUT_HOME/bin:$MAHOUT_HOME/conf

6、复制

cp –f /home/hadoop/hadoop-core-1.2.1.jar/home/hadoop/hbase-0.94.16/lib/

cd/home/hadoop/hbase-0.94.16/lib

rm -f hadoop-core-1.0.4.jar

scp -rhbase-0.94.16 hadoop@hadoop5:/home/hadoop/

scp -rhbase-0.94.16 hadoop@hadoop6:/home/hadoop/

7、启动hbase

[hadoop@hadoop4bin]$ start-hbase.sh

2 用HBase存储社交网站站内短信信息，要求记录发送者，接受者，时间，内容，有关的查询是发送者可以列出他所有（或按时间段）发出的信息列表（按时间降序排列），接收者可以列出他所有（或按时间段）收到的信息列表（按时间降序排列）。请进行数据建模。

构建两张表：

第一张：sender_t 以 senderid+sendtime 为row key,info为列簇,列为：senderid,receiveid,message,sendtime

第二张：receiver_t 以receiverid+receivetime为row key ,info为列簇，列为

senderid,Receiverid,message,receivetime

降序排列rowkey的设计方案为：

Long.MAX_VALUE -<date-as-long>
