Subject [jira] [Created] (PIG-4517) builtin UDF for mass concat of strings

-------------------------------------

             Summary: builtin UDF for mass concat of strings
                 Key: PIG-4517
                 URL: https://issues.apache.org/jira/browse/PIG-4517
             Project: Pig
          Issue Type: New Feature
          Components: piggybank
            Reporter: Pracheer Agarwal
            Priority: Minor


Right now we have CONCAT UDF which concatenate two strings. We don't have any UDF for mass
concatenation. The functionality of the proposed udf can be exact reverse of STRSPLIT. 

STRSPLIT take a string and a regex and return a tuple of strings. On the same line MASSCONCAT
can take a tuple and a delimeter as inputs and return a string as output.

Example:

Inputs - (a,b,c,d), "|"
Output - a|b|c|d
