------------------------------
Summary: DROP TABLE throws any error/warning while an attempt is
made to drop a table which does not exist .
Key: HIVE-20288
URL: https://issues.apache.org/jira/browse/HIVE-20288
Project: Hive
Issue Type: Bug
Affects Versions: 2.1.1, 1.2.1
Reporter: vaibhav
When I do DROP TABLE ( for a table which really does not exist in the database)
in hive .It really don't throw any warning/error and just show OK (the same
message as the table is present and was dropped ).
=========
hive> show tables;
OK
Time taken: 0.921 seconds
hive>
> drop table tabledoesnotexist;
OK
Time taken: 0.355 seconds
========
hive> create table test(id int);
OK
Time taken: 1.258 seconds
hive> drop table test;
OK
Time taken: 0.561 seconds
In general, the database should return an Error if the table is not present.
Eg : MySQL:
mysql> drop table test;
[Code: 1051, SQL State: 42S02] Unknown table 'test'
