Description

Synopsis:
=========
Query option to restrict the execution of risky queries.

Feature Request:
================
Please enahnce Impala with a query option to restrict the execution of risk queries.

For instance, in Hive, the parameter "set hive.mapred.mode=strict" will reject queries based in the following criteria:

1) Queries on partitioned tables are not permitted unless they include a partition filter in the WHERE clause.

2) Queries doing Cartesian product (cross join).
