date_format(date/timestamp/string ts, string fmt): string

Converts a date/timestamp/string to a value of string in the format specified by the date format fmt (as of Hive 1.2.0). Supported formats are Java SimpleDateFormat formats – https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html. The second argument fmt should be constant. Example: date_format('2015-04-08', 'y') = '2015'.
date_format can be used to implement other UDFs, e.g.:
dayname(date) is date_format(date, 'EEEE')
dayofyear(date) is date_format(date, 'D')
