0: jdbc:hive2://10.18.18.214:23040/default> show functions like addm_3;
+-----------------+--+
| function |
+-----------------+--+
| addm_3 |
| default.addm_3 |
+-----------------+--+
2 rows selected (0.047 seconds)
0: jdbc:hive2://10.18.18.214:23040/default>
When show function executed it is listing both the function but what about the
db for permanent function when user has not specified.
Duplicate should not be allowed if user creating temporary one with the same
name.
