[jira] [Comment Edited] (DATAFU-92) Create UDF to extract tuple out
of bag in a specified index
[ https://issues.apache.org/jira/browse/DATAFU-92?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14585172#comment-14585172 ]

--------------------------------------------------------------
Actually the third parameter can have other values then null.
As a matter of fact I already implemented the UDF and tested it, but didn't got the time to align my environment for submitting the code (and probably won't have the time soon). So I attached to this issue the code + example for the third parameter, to be used as a reference for your implementation.
Please see attached files.

> Create a new UDF that is similar to "FirstTupleFromBag" but this one will be more general, and not only the first tuple.
> This new UDF can be called "TupleFromBag" and will get three parameters:
> 1. DataBag
> 2. Index
> 3. Optional Default Tuple
> There should be a consideration to refactor FirstTupleFromBag to call TupleFromBag, for reusability consideration.
