hive使用map字段

create table role_bigtable(table_name string, record_date string, server_id string, map_col map<string, string>)  
partitioned by ( dt string, game_id string)
ROW FORMAT DELIMITED                                          
FIELDS TERMINATED BY '\t'                                
COLLECTION ITEMS TERMINATED BY ','                       
MAP KEYS TERMINATED BY ':'; 

创建 test7.txt

role_info    2017-01-01    101    accoount_id:20, role_id:30
role_info    2017-01-01    102    accoount_id:201, role_id:301

导入数据

load data local inpath '/home/hadoop/test/test7.txt' 
into table role_bigtable
partition (dt = '2017-01-01', game_id='gcd')

查询

 select perf["accoount_id"] from role_bigtable where dt='2017-01-01' and game_id = 'gcd';
