ATTACHMENT ID: 12690294 - PreCommit-HIVE-TRUNK-Build
> Fastpath for limited fetches from unpartitioned tables
> ------------------------------------------------------
>
> Key: HIVE-9255
> URL: https://issues.apache.org/jira/browse/HIVE-9255
> Project: Hive
> Issue Type: Bug
> Components: Physical Optimizer
> Affects Versions: 0.14.0, 0.15.0
> Reporter: Gopal V
> Assignee: Gopal V
> Priority: Minor
> Attachments: HIVE-9255.1.patch
>
>
> Currently, for flat tables, the threshold check is applicable for a query
> like {{select * from lineitem limit 1;}}.
> This is not necessary as without a filter clause, this can be executed
> entirely via FetchTask. Running a cluster task is redundant for this case.
> This fastpath is applicable for partitioned tables already.
