无法查看mysql设置中的所有配置单元Metastore表

Question

我的机器上有apache Hive - 0.12.0和hadoop - 1.2.1版本。 和使用mysql的配置单元Metastore。

现在，当我为Metastore测试启动显示表时，它只显示20行/表格。

// 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) 

为什么不能看到像下面那样的所有表格。我是否需要为此使用任何其他配置单元版本？请建议。

尝试通过可用的sql脚本（在你的情况下为mysql）升级配置单元架构。

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格。它应该显示所有的表格。

mysql> show tables;
