Hi, I have a question about HIVE-3675 NaN does not work correctly for round(n). The issue did solve the NaN problem, but the hql below result in a different display with hive0.10. I checked the code UDFRound.java, found the function "LongWritable evaluate(DoubleWritable n)" changed to "DoubleWritable evaluate(DoubleWritable n) ". I think it maybe better to add a "LongWritable evaluate(LongWritable n)" function and modify the toString function of LongWritable that could solve the problem.
select round(1234560), round(12345670) from test limit 1; //hive 0.10 1234560.0 1.234567E7 //hive 0.9 1234560 12345670 select round(cast(1234560 as BIGINT)), round(cast(12345670 as BIGINT)) from test limit 1; //hive 0.10 1234560.0 1.234567E7 regards, chenchun
