HBase实战（3）：使用HIVE SQL 操作分布式集群HBASE

使用HIVE  SQL操作分布式集群HBASE：

1，在Hive中创建HBase识别的表 

hive>     
    > 
    > CREATE EXTERNAL  TABLE hbase_hive_.....tion(rowkey string, info map)   
    > STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'   
    > WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,info:")   
    > TBLPROPERTIES ("hbase.table.name" = "db_r......._operation");  
OK
Time taken: 0.959 seconds

2，hive连接Hbase，查询数据：
