Jason Dere commented on HIVE-6327: ---------------------------------- Maybe the function signature matching for non-generic UDFs should allow decimal args to be converted to double for these UDFs? Would be a more general fix as opposed to having to patch each of these UDFs. > A few mathematic functions don't take decimal input > --------------------------------------------------- > > Key: HIVE-6327 > URL: https://issues.apache.org/jira/browse/HIVE-6327 > Project: Hive > Issue Type: Improvement > Affects Versions: 0.11.0, 0.12.0 > Reporter: Xuefu Zhang > Assignee: Xuefu Zhang > > A few mathematical functions, such as sin() cos(), etc. don't take decimal as > argument. > {code} > hive> show tables; > OK > Time taken: 0.534 seconds > hive> create table test(d decimal(5,2)); > OK > Time taken: 0.351 seconds > hive> select sin(d) from test; > FAILED: SemanticException [Error 10014]: Line 1:7 Wrong arguments 'd': No > matching method for class org.apache.hadoop.hive.ql.udf.UDFSin with > (decimal(5,2)).
