Description

Alter table renames was recently refactored. This introduced a bug where rename to a different database is not applied correctly.

Steps to reproduce:

From Hive:

create database bug1;

create table bug1.foo (id int);

create database bug2;

alter table bug1.foo rename to bug2.foo;

 

From Impala:

use bug2;

show tables;

 

Expect foo to show up in bug2, it doesn't.
