please consider not writing a new UDF and instead using the following syntax with built-in UDFs itself .
SELECT from_unixtime(unix_timestamp('07/Dec/2014:23:59:04','dd/MMM/yyyy:HH:mm:ss'), 'dd-MMM-yyyy HH:mm:ss') FROM twitter_data_raw LIMIT 1; feel free to play around with the formats to get desired results regards Devopam On Thu, Jan 29, 2015 at 3:12 PM, Nagarjuna Vissarapu < nagarjuna.v...@gmail.com> wrote: > Hi All, > > I wrote hive UDF to convert > > 07/Dec/2014:23:59:04 to 07-Dec-2014 23:59:04 > > I attached UDF.
