在实现过程中，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路径我遇到以下异常，因为无法识别alter database语句中数据库集位置附近的输入我创建的数据库正在使用它创建表。
请帮助纠正的可能性和解决这个问题。此时此刻，我正在创建另一个数据库，具体位置如下
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
Time taken: 0.145 seconds, Fetched: 1 row(s)

hive> use db_mig;
OK
Time taken: 0.258 seconds
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';
