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