Description
A few mathematical functions, such as sin() cos(), etc. don't take decimal as argument.
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)).
