Subject [jira] Commented: (PIG-559) ARITY and SIZE function produce wrong value for tuples
Date Fri, 12 Dec 2008 00:49:44 GMT

    [ https://issues.apache.org/jira/browse/PIG-559?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12655831#action_12655831

Pradeep Kamath commented on PIG-559:

+1 - the only comment is whether the following check is required :
if (input == null || input.size() == 0)
            return null;

In POUserFunc if the input is not directly attached to POUserFunc, it create a new Tuple and
fills it with the getNext() result of its input. To my knowledge currently the POUserFunc
will not be the root of Foreach inner plan and hence input should not be directly attached.
So could these checks be avoided?

> As Santhosh pointed out the problem is that instead of taking the first element of the
input tuple and applying size to it, the code just applices the size to the input tuple which
is always 1.
