Tim Armstrong updated IMPALA-8103:
----------------------------------
Target Version: Product Backlog
Priority: Minor (was: Major)
> Plan hints show up as "--" comments in analysed query
> -----------------------------------------------------
>
> Key: IMPALA-8103
> URL: https://issues.apache.org/jira/browse/IMPALA-8103
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Reporter: Tim Armstrong
> Assignee: Andrew Sherman
> Priority: Minor
>
> I noticed that the hints added in IMPALA-5821 show up in the -- style rather
> than /**/
> {code}
> Sql Statement: select * from tpch.lineitem join /*+ broadcast */
> tpch.part on l_partkey = p_partkey limit
> ...
> Analyzed query: SELECT * FROM tpch.lineitem INNER JOIN
> -- +broadcast
> tpch.part ON l_partkey = p_partkey LIMIT CAST(5 AS TINYINT)
> {code}
> I guess this works and maybe its fine, but I was really confused when I saw
> it. It looks like getPlanHintsSql() uses this to generate views in such a way
> that Hive will ignore the hints, but that concern doesn't seem relevant to
> this use case.
