我使用Cloudera Manager将CDH从5.0.0 beta升级到5.2.1。除hive Metastore外，所有服务都正常运行。我正在使用MySQL来进行蜂巢状的Metastore。
当我触发查询时，我无法从配置单元中删除表：
`drop table test;`
我收到以下错误。
hive> drop table test;

参考链接
有人可以提出建议吗？
答案 0 :(得分：1)
我有完全相同的问题。我尝试做参考链接中建议的内容，但我仍然遇到了同样的问题（即使我修复了运行脚本时可以看到的所有错误）。
最后，我在Hive Metastore脚本中查找了BIG_DECIMAL_HIGH_VALUE，我在以下create语句中的每个hive-schema-0.1 * .0.mysql.sql中都看到了它：

`CS_ID` bigint(20) NOT NULL,

当我在Hive Metastore数据库中检查这些表时，我得到了不同的东西：

因为两个表都是空的，我只是删除并再次创建它们，并在hive-schema-0.13.0.mysql.sql文件中列出了create语句。
这样做之后，我可以再次删除Hive表。
