mysql> show databases;

+--------------------+

| Database           |

+--------------------+

| information_schema |

| mysql              |

| performance_schema |

| sys                |

4 rows in set (0.00 sec)

 

10.建立Hive須要的數據庫

mysql> create database if not exists hive_metadata;

Query OK, 1 row affected (0.01 sec)



mysql> show databases;

+--------------------+

| Database           |

+--------------------+

| information_schema |

| hive_metadata      |

| mysql              |

| performance_schema |

| sys                |

5 rows in set (0.00 sec)

 

爲hive_metadata設置權限

grant all privileges on hive_metadata.* to 'hive'@'%' identified by 'hive';

grant all privileges on hive_metadata.* to 'hive'@'locaclhost' identified by 'hive';

grant all privileges on hive_metadata.* to 'hive'@'centos-master' identified by 'hive';
