Subject [jira] [Commented] (HIVE-3850) hour() function returns 12 hour clock value when using timestamp datatype
Date Mon, 11 Feb 2013 04:13:13 GMT


Arun A K commented on HIVE-3850:

Hello  []

There is a patch already available with the suggested changes made, submitted by Mr. [~710154].
So what is the point in submitting the same patch again ? More over there is a pending review
request for the same . Request you to justify your act?
Have you tried to include something different in the previous work?

> Apparently 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?
