Adrian Wang created HIVE-26174:
----------------------------------
Summary: ALTER TABLE RENAME TO should check new db location
Key: HIVE-26174
URL: https://issues.apache.org/jira/browse/HIVE-26174
Project: Hive
Issue Type: Improvement
Reporter: Adrian Wang
Assignee: Adrian Wang
Currently, if we run
ALTER TABLE db1.table1 RENAME TO db2.table2;
and with `db1` and `db2` on different filesystem, for example `db1` as
`"hdfs:/user/hive/warehouse/db1.db"`, and `db2` as
`"s3://bucket/s3warehouse/db2.db"`, the new `db2.table2` will be under location
`hdfs:/s3warehouse/db2.db/table2`, which looks quite strange.
The idea is to ban this kind of operation, as we seem to intend to ban that,
but the check was done after we changed file system scheme so it was always
true.
