我将配置单元配置为使用mysql元存储。它很好用

但是,当我试图删除一个表时,我会出现如下错误

FAILED: Error in metadata: javax.jdo.JDODataStoreException: Error(s) were found while auto-creating/validating the datastore for classes. The errors are printed in the log, and are attached to this exception.
NestedThrowables:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Specified key was too long; max key length is 767 bytes
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
我做了一些研究,谷歌告诉我改变mysql字符集设置可以解决这个问题

我的mysql设置如下

mysql> show variables like '%char%';
+--------------------------+----------------------------------------+
| Variable_name            | Value                                  |
+--------------------------+----------------------------------------+
| character_set_client     | utf8                                   |
| character_set_connection | utf8                                   |
| character_set_database   | utf8                                   |
| character_set_filesystem | binary                                 |
| character_set_results    | utf8                                   |
| character_set_server     | utf8                                   |
| character_set_system     | utf8                                   |
| character_sets_dir       | /usr/local/mysql/share/mysql/charsets/ |
+--------------------------+----------------------------------------+
8 rows in set (0.02 sec)
我将所有字符集设置从
utf8
更改为
latin1
,除了
字符集文件系统
字符集目录

即使这样做,我在尝试删除表时仍然会遇到相同的错误。 更糟糕的是,每当我创建一个新表时,mysql字符集设置都会重置为
utf-8


有人能帮忙吗

问题在于,在hive-site.xml中,它在创建下面的“hive”时使用了其他数据库

 <property>
 <name>javax.jdo.option.ConnectionURL</name>
 <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>
 </property>

javax.jdo.option.ConnectionURL
jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true
将您已经在mysql中创建的数据库名称更改为“metastore”,如下所示

<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/metastore?createDatabaseIfNotExist=true</value>
</property>

javax.jdo.option.ConnectionURL
jdbc:mysql://localhost:3306/metastore?createDatabaseIfNotExist=true
希望这个问题我也有同样的问题,我就这样解决了。 弗林德利马托克
