-----------------------------------
The above failed test case is flaky, which is unrelated code changes in the
patch. Patch is ready for review.

> 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)). Possible choices: _FUNC_(double)
> {code}
> HIVE-6246 covers only sign() function. The remaining ones, including sin,
> cos, tan, asin, acos, atan, exp, ln, log, log10, log2, radians, and sqrt.
> These are non-generic UDFs.
