(Updated May 15, 2018, 11:18 p.m.) Review request for hive, Peter Vary, Sahil Takiar, and Vihang Karajgaonkar. Changes ------- Changing the patch with new logic. Adding an additional optional parameter dateFormat, which can provide output format that user expects. The default format is kept as the existing one, YYYY-MM-dd. Hence, the patch is backward compatible, and also capable of handling different input and output formats as required by the user. Also, now the code format is consistent with the other similar UDFs MonthsBetween and GenericUDFDateFormat. Added unit tests to check various cases. Thanks Peter for helping me reach a conclusion on what logic I need to use. I have updated the UDF description. Will update the docs once the patch is approved. Repository: hive-git Description ------- Adding support to retain the time part (HH:mm:ss) for add_months UDF when the input is given as timestamp format.
