Description

Repro:

CREATE DATABASE a;
CREATE DATABASE b;

CREATE TABLE a.test1 (a string);
INSERT INTO a.test1 (a) VALUES ("a");
COMPUTE STATS a.test1;
DROP TABLE a.test1; <-- this works

CREATE TABLE a.test2 (a string);
INSERT INTO a.test2 (a) VALUES("b");
COMPUTE STATS a.test2;
ALTER TABLE a.test2 RENAME TO b.test2;
DROP TABLE b.test2; <-- this line fails with the stack trace originally posted

ALTER TABLE b.test2 RENAME to a.test2; #move table back to original location
DROP TABLE a.test2; <-- this now works

DROP DATABASE a;
DROP DATABASE b;
