> Fix logic introduced in HIVE-20660 to estimate statistics for group by
> ----------------------------------------------------------------------
>
> Key: HIVE-20842
> URL: https://issues.apache.org/jira/browse/HIVE-20842
> Project: Hive
> Issue Type: Bug
> Components: Statistics
> Affects Versions: 4.0.0
> Reporter: Vineet Garg
> Assignee: Vineet Garg
> Priority: Major
> Attachments: HIVE-20842.1.patch, HIVE-20842.2.patch
>
>
> HIVE-20660 introduced better estimation for group by operator. But the logic
> did not account for Partial and Full group by separately.
> For partial group by parallelism (i.e. number of tasks) should be taken into
> account.
