[jira] [Commented] (IMPALA-6950) Restrict execution of queries that don't include a partition filter or do a cross join

["Tim Armstrong (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IMPALA-6950?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16535216#comment-16535216 ] 

Tim Armstrong commented on IMPALA-6950:
---------------------------------------

I think the ask is reasonable, but we should make sure to make the behaviour consistent with other Impala options rather than mimicking Hive.

>          Issue Type: Sub-task
>          Components: Frontend
>    Affects Versions: Impala 2.11.0

> 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).
