[jira] [Commented] (PIG-3014) CurrentTime() UDF has undesirable characteristics

["Julien Le Dem (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-3014?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13507750#comment-13507750 ] 

Julien Le Dem commented on PIG-3014:
------------------------------------

I think it's better to have one test class per UDF.
Usually tests are grouped per class or functional group of classes.
All builtin UDFs do not make a functional group as they have various different purposes. It just makes a huge Test class which is undesirable.

> As part of the explanation of the new DateTime datatype I noticed that we had added a CurrentTime() UDF. The issue with this UDF is that it returns the current time _of every exec invocation_, which can lead to confusing results. In PIG-1431 I proposed a way such that every instance of the same NOW() will return the same time, which I think is better. Would enjoy thoughts.
