mysql - 无法在 mysql 设置中查看所有配置单元元存储表

Question

我的机器上有 apache Hive - 0.12.0 和 hadoop - 1.2.1 版本。并将 mysql 用于 hive 元存储。

现在，当我为 Metastore 测试触发 show tables 时，它只显示 20 行/表。

// My Environment
mysql> use metastore_db
Database changed
mysql> show tables;
+---------------------------+
| Tables_in_metastore_db    |
+---------------------------+
| BUCKETING_COLS            | 
| CDS                       | 
| COLUMNS_V2                | 
| DATABASE_PARAMS           | 
| DBS                       | 
| PARTITION_KEYS            | 
| SDS                       | 
| SD_PARAMS                 | 
| SEQUENCE_TABLE            | 
| SERDES                    | 
| SERDE_PARAMS              | 
| SKEWED_COL_NAMES          | 
| SKEWED_COL_VALUE_LOC_MAP  | 
| SKEWED_STRING_LIST        | 
| SKEWED_STRING_LIST_VALUES | 
| SKEWED_VALUES             | 
| SORT_COLS                 | 
| TABLE_PARAMS              | 
| TBLS                      | 
| VERSION                   | 
+---------------------------+
20 rows in set (0.06 sec)

为什么看不到下面的所有表格。我需要为此使用任何其他配置单元版本吗？请建议。

尝试通过可用的 sql 脚本（在您的情况下为 mysql）升级配置单元模式。

mysql> use metastore_db
Database changed

mysql> SOURCE $HIVE_HOME/scripts/metastore/upgrade/mysql/hive-schema-0.12.0.mysql.sql;

mysql> CREATE USER 'dbuser'@'%' IDENTIFIED BY 'dbpassword'; 

mysql> GRANT all on *.* to 'dbuser'@localhost identified by 'dbpassword';

mysql> flush privileges;

现在重新查询您的表。它现在应该显示所有表格。

mysql> show tables;
