Same test case, only t2 already exists; very different stack trace:

SET spider_same_server_link = on;

eval create server s foreign data wrapper mysql options (host "127.0.0.1", database "test", user "root", port $MASTER_MYPORT);

CREATE TABLE t2 (x INT);

CREATE OR REPLACE TABLE t2 AS SELECT a FROM t1_SPIDER;

# Cleanup
