[jira] [Created] (SPARK-8256) string function: regexp_replace

Reynold Xin created SPARK-8256:
----------------------------------

             Summary: string function: regexp_replace
                 Key: SPARK-8256
                 URL: https://issues.apache.org/jira/browse/SPARK-8256
             Project: Spark
          Issue Type: Sub-task
            Reporter: Reynold Xin


regexp_replace(string INITIAL_STRING, string PATTERN, string REPLACEMENT): string

Returns the string resulting from replacing all substrings in INITIAL_STRING that match the java regular expression syntax defined in PATTERN with instances of REPLACEMENT. For example, regexp_replace("foobar", "oo|ar", "") returns 'fb.' Note that some care is necessary in using predefined character classes: using '\s' as the second argument will match the letter s; '\\s' is necessary to match whitespace, etc.
