Ganesha Shreedhara updated HIVE-12719:
--------------------------------------
Release Note: Currently function name for the permanent function is getting
formed as dbName.WINDOW_FUNC_PREFIX+functionName where as function registry has
function name as WINDOW_FUNC_PREFIX+dbName.functionName. This is leading to
invalid function error when we use permanent function with window function. Fix
has been done such that we form the permanent function name rightly as
WINDOW_FUNC_PREFIX+dbName+.+functionName so that it matches with the name in
function registry. The functionality for built-in/temporary function would
remain the same. (was: We will get invalid function error when permanent
function is used along with window function because the permanent function is
stored as db_name.function_name in the function registry where as
built-in/temporary function gets stored without any prefix in the function
registry.
The fix is done such that the we will first form the qualified name for the
permanent function and then compare if it exists in function registry. )
> As a hive user, I am facing issues using permanent UDAF's.
