> Key: PIG-3870
> URL: https://issues.apache.org/jira/browse/PIG-3870
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.12.0
> Reporter: Praveenesh Kumar
> Assignee: karan kumar
> Fix For: 0.12.0

>
> I had a scenario, which required me to change the STRSPLIT code. The scenario
> was as follows:
> I have a data like:
> 1 A|1|1 some
> 2 B|2|2 data
> 3 C|3|3 hadoop
> Need output like this :
> 1 A some
> 1 1 some
> 1 1 some
> 2 B data
> 2 2 data
> 2 2 data
> 3 C hadoop
> 3 3 hadoop
> 3 3 hadoop
> I was trying to use STRSPLIT($1,'\\\|') which was returning a tuple, If I do
> flatten on it, it converts the data into columns.
> If we return a bag of tuples, we can easily use flatten() to convert it into
> rows, plus can also convert that into Tuple using TOTUPLE() UDF (if someone
> just want to use it as tuple)
> After the suggestion from [~daijy], I am creating a JIRA ticket to create a
> new UDF STRSPLITTOBAG, which will return a bag of tuples as suggested above.
