             Summary: string function: substring_index
                 Key: SPARK-8264
                 URL: https://issues.apache.org/jira/browse/SPARK-8264
             Project: Spark
          Issue Type: Sub-task
            Reporter: Reynold Xin


substring_index(string A, string delim, int count): string



Returns the substring from string A before count occurrences of the delimiter delim (as of Hive 1.3.0). If count is positive, everything to the left of the final delimiter (counting from the left) is returned. If count is negative, everything to the right of the final delimiter (counting from the right) is returned. Substring_index performs a case-sensitive match when searching for delim. Example: substring_index('www.apache.org', '.', 2) = 'www.apache'.
