Mysql 配置单元元存储服务器（CDH）启动失败

最近我安装了CDH hadoop（版本5.14.2），但无法启动HIVE Metastore服务器

它有一个

HiveServer2

和一个

HIVE Metastore服务器

当我启动它时，我设置了

datanucleus.autoCreateSchema

true

，让hive自己创建表

然后，HiveServer2启动良好，但HIVE Metastore服务器失败。下面是日志

我不知道如何解决

列长度对于列'PARAM_VALUE'太大的问题

我应该在mysql中添加一些设置吗（我使用yum安装5.6.40版）

提前感谢。

MySQL的最大行大小限制为65535（减去存储开销）字节。如果在字符集中（例如：UTF-8），一个字符最多占用3个字节，则varchar列的最大大小可以是65535/3=~21845，假设它是表中唯一的列。 这一点在

将字符集更改为最大长度为1的latin1可以解决此问题，因为在latin1中，列大小的最大值约为65535

连接到Hive Metastore DB（MYSQL）并运行 ALTER数据库字符集1
