[jira] [Created] (IMPALA-5313) Allow query hints to be submitted via SET

Balazs Jeszenszky created IMPALA-5313:
-----------------------------------------

             Summary: Allow query hints to be submitted via SET
                 Key: IMPALA-5313
                 URL: https://issues.apache.org/jira/browse/IMPALA-5313
             Project: IMPALA
          Issue Type: New Feature
          Components: Frontend
            Reporter: Balazs Jeszenszky


It is often not feasible/inconvenient to alter the query text to include hints. In particular, this is painful when trying to work around suboptimal join ordering using BI tools. Being able to issue:

SET STRAIGHT_JOIN=1;

(or similar)
would be a good way to work around this.
