StanZhai updated SPARK-21318:
-----------------------------
Description:
The function actually exists, but the exception message is:
{code}
This function is neither a registered temporary function nor a permanent
function registered in the database 'default'.
{code}
My UDF has already been registered in the current database. But it's failed to
init during lookupFunction.
The exception message should be:
{code}
No handler for Hive UDF 'site.stanzhai.UDAFXXX':
org.apache.hadoop.hive.ql.exec.UDFArgumentLengthException: Two arguments is
expected
{code}
This is not conducive to positioning problems.
