> While there are continuous efforts in extending Hive’s SQL support (e.g., see some recent examples such as HIVE-2005 and HIVE-2810), many widely used SQL constructs are still not supported in HiveQL, such as selecting from multiple tables, subquery in WHERE clauses, etc.  
> We propose to build a SQL-92 full compatible engine (for MapReduce based analytical query processing) as an extension to Hive. 
> The SQL frontend will co-exist with the HiveQL frontend; consequently, one can  mix SQL and HiveQL statements in their queries (switching between HiveQL mode and SQL-92 mode using a “hive.ql.mode” parameter before each query statement). This way useful Hive extensions are still accessible to users.
