> Enabling native fast hash table can cause incorrect results
> -----------------------------------------------------------

> Key: HIVE-12562
> URL: https://issues.apache.org/jira/browse/HIVE-12562
> Project: Hive
> Issue Type: Bug
> Reporter: Siddharth Seth
> Assignee: Matt McCline
>
> Enabling "hive.vectorized.execution.mapjoin.native.fast.hashtable.enabled"
> causes incorrect results when running with LLAP.
> I believe this does not happen for simple container runs. However, it's
> possible that caching of these tables, or using the same table more than once
> causes issues - which may be seen with container reuse.
> The results vary by a small percentage.
> e.g. 82270, 82267 <- Two results for the same query run back to back.
