Guess there is no need for a test case since the change is minor. > hour() function returns 12 hour clock value when using timestamp datatype > ------------------------------------------------------------------------- > > Key: HIVE-3850 > URL: https://issues.apache.org/jira/browse/HIVE-3850 > Project: Hive > Issue Type: Bug > Components: UDF > Affects Versions: 0.9.0 > Reporter: Pieterjan Vriends > Attachments: HIVE-3850.patch.txt > > > Apparently UDFHour.java does have two evaluate() functions. One that does accept a Text object as parameter and one that does use a TimeStampWritable object as parameter. The first function does return the value of Calendar.HOUR_OF_DAY and the second one of Calendar.HOUR. In the documentation I couldn't find any information on the overload of the evaluation function. I did spent quite some time finding out why my statement didn't return a 24 hour clock value. > Shouldn't both functions return the same? -- This message is automatically generated by JIRA.
