无法识别配置单元中 alter database 语句中数据库 SET LOCATION 附近的输入

Question

在实施过程中，尝试更改配置单元中现有数据库的 HDFS 路径，

从特定路径更改 /apps/hive/warehouse/ HDFS 路径我收到以下异常 无法识别数据库附近的输入 SET LOCATION in alter database声明 我创建的数据库正在使用它创建 table table_mig。

请帮助纠正此问题的可能性并修复。此时此刻，我正在创建另一个带有 LOCATION 的数据库，特别是 as

创建数据库db_migg LOCATION '/sit/dwh/hdata/db_migg';

hive> describe database db_mig;
OK
db_mig              hdfs://nnscbhaastest/apps/hive/warehouse/db_mig.db  hiveuser       USER

hive> use db_mig;
OK

hive> show tables;
OK
table_mig
Time taken: 0.163 seconds, Fetched: 1 row(s)

hive> ALTER DATABASE db_mig SET LOCATION '/sit/dwh/hdata/db_mig';

Answer 1

看来您使用的是旧版本的 HIVE。您需要 HIVE 版本 2.2.1、2.4.0 或更高版本。请检查 hive wiki for more.

如果您使用的是较低版本的 hive，请尝试使用更改位置删除并重新创建数据库，而不是在 ALTER 脚本中使用它，如下所示：

CREATE DATABASE db_mig LOCATION '/sit/dwh/hdata/db_mig';
