Jason Dere commented on HIVE-5203: ---------------------------------- Managed to add some tests by moving the new functionality to a separate method, though we'd never hit those scenarios in real life. Also posted the changes at https://reviews.facebook.net/D12711 > FunctionRegistry.getMethodInternal() should prefer method arguments with > closer affinity to the original argument types > ----------------------------------------------------------------------------------------------------------------------- > > Key: HIVE-5203 > URL: https://issues.apache.org/jira/browse/HIVE-5203 > Project: Hive > Issue Type: Bug > Components: Types, UDF > Reporter: Jason Dere > Assignee: Jason Dere > Attachments: HIVE-5203.1.patch, HIVE-5203.2.patch > > > When the function registry is trying to determine the best version of UDF > evaluate() to use based on a set of arguments passed in, it should prefer > methods where the argument types are more related to the original types. For > example if varchar is used with UDFFromUnixTime(), varchar is convertible to > both the double and string versions of evaluate() for that UDF. In this case > we would prefer that the function registry select the string version over the > double version, since varchar and string are both string types. > This doesn't really affect any of the existing types, but comes into play > with the addition of the varchar type (HIVE-4844). -- This message is automatically generated by JIRA.
