Description

OR clause is evaluated incorrectly in Hive query when the where the condition is evaluated as FALSE or TRUE. If we reverse the condition checks and it is evaluated as TRUE OR FALSE, it works fine.

Steps to repro :

  CREATE TABLE `rtfnprepro1`(                                                   
  `id` int,                                                                 
  `name` string,                                                            
  `zip` int,
