Rhive环境搭建问题

1. 安装好 R, hive 后测试 命令行输入 命令能进入控制台，且无错误

2. 在R控制台安装rJava, RHive(install.packages(''))

3. 在命令汉中启动hive thift server,  nohup hive --service hiveserver &

4. libary(RHive)引入包后适应 rhive.connect(host='IP', hiveserver2=FALSE) 不加红色这个这个老出错(和版本有问题我的版本是R 3.02 + hive 0.12 + hadoop2.2)

5. 列出所有hive表 rhive.list.tables()

6. 查看hive表结果 rhive.desc.table('table')

7. hive 查询 rhive.query('sql')

8. hive 查询hdfs目录， rhive.hdfs.ls()

9. hive查询文件 rhive.hdfs.cat('')

10. 关闭连接 rhive.close()

11. Rhive 函数库
