java操作hbase1.3.1的增删改查

我的eclipse程序在windows7机器上，hbase在linux机器上

1，首先在C:\Windows\System32\drivers\etc下面的HOSTS文件，加上linux 集群



2.直接附上代码：

}
table.close();
close();
}

}

3.项目下面还要放上linux环境上配置hadoop和hbase配置文件，hbase-site.xml和hdfs-site.xml，下面是我项目的简单结构



4.按要求贴上pom.xml文件，我这项目还用了hive,redis连接，所以pom.xml写的jar比较多，但其实只需要hbase连接的jar就行
