László Bodor updated HIVE-26003:
--------------------------------
Description:
DROP FUNCTION silently passes when a function doesn't exist, which is bad,
especially because hive has "DROP FUNCTION IF EXISTS".
I was working with functions when I found that "DROP FUNCTION myfunc" passed,
and I thought it simply dropped the function, but then it kept working. I
realized I was supposed to call "DROP FUNCTION default.myfunc" because it's
registered as "default.myfunc". This is just one example where DROP FUNCTION
seems to work expected, but silently makes confusion.
