Vineet Garg commented on HIVE-18891:
------------------------------------

[~amitchauhan1203] Hive 1.2.1 doesn't support these kind of queries (subqueries 
with OR predicate). You need to use Hive 2.2.0 or up to execute these queries 
(see HIVE-18167, HIVE-15481)

> I am trying to write a basic  query in hive and it is giving me error
