The GROUP operator in Pig is a 'blocking' operator, and forces a Hdoop Map-Reduce job. The last element of the result tuple will contain all input after the last match. By default, Pig Latin statements are processed using multi-query execution. Use the STRSPLIT function to split a string around matches of a given regular expression. to convert values (default=Utf8StorageConverter). The backward search for the character begins at the end of the string. Valid values for the hash functions are 'jenkins' and 'murmur'.
