---------------------------------
Summary: 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: 0.12.0, 0.11.0
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)). Possible choices: _FUNC_(double)
{code}
HIVE-6246 covers only sign() function. The remaining ones, including sin, cos,
tan, asin, acos, atan, exp, log, log10, log2, radians, and sqrt. These are
non-generic UDFs.
