I have one question tho. Earlier, function names were identifier. I assume DOT can be part of an identifier. If so, than can it be a problem now if some one who has earlier created a function name with dot in it, may now confuse Hive. > Allow user-defined functions to be qualified with database name > --------------------------------------------------------------- > > Key: HIVE-6167 > URL: https://issues.apache.org/jira/browse/HIVE-6167 > Project: Hive > Issue Type: Sub-task > Components: UDF > Reporter: Jason Dere > Assignee: Jason Dere > Attachments: HIVE-6167.1.patch, HIVE-6167.2.patch, HIVE-6167.3.patch, HIVE-6167.4.patch > > > Function names in Hive are currently unqualified and there is a single namespace for all function names.
