Project: Pig
Issue Type: New Feature
Components: internal-udfs
Reporter: Yuxiang Wang
Assignee: Yuxiang Wang
Fix For: 0.17.0
A new Pig UDF *STRING_SEARCH_ALL* that Implementing regex for searching
keyword(substring) in a line of string, and all matched substrings will be
stored as individual tuples in a bag, i.e.{code} output: ({(a),(b),(c)}){code}
