Subject [jira] [Created] (PIG-2929) CONCAT returns null when 1 items is null
Date Mon, 24 Sep 2012 14:38:07 GMT
Nicholas Verbeck created PIG-2929:

             Summary: CONCAT returns null when 1 items is null
                 Key: PIG-2929
                 URL: https://issues.apache.org/jira/browse/PIG-2929
             Project: Pig
          Issue Type: Bug
          Components: documentation, internal-udfs
    Affects Versions: 0.9.2, 0.9.1, 0.9.0
            Reporter: Nicholas Verbeck

Just stumbled upon this issue over the weekend. It appears the built-in CONCAT function will
return null in the advent of 1 item in the Tuple being null. If this is as intended it would
be nice if the docs made note of this. Otherwise it would be nice if nulls where just skipped
and a proper string of what was left was returned. If all items are null then just return
null in that case.
