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
Fix For: 0.15.0
Attachments: HIVE-9255.1.patch, HIVE-9255.2.patch, HIVE-9255.3.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.
