-----------------------------------------
Summary: Partioned and unpartitioned tables should be treated if
optimize_partition_key_scans is enabled and we are scanning zero slots
Key: IMPALA-5320
URL: https://issues.apache.org/jira/browse/IMPALA-5320
Project: IMPALA
Issue Type: Bug
Components: Frontend
Affects Versions: Impala 2.9.0
Reporter: Taras Bobrovytsky
Assignee: Taras Bobrovytsky
Priority: Minor
Currently the planner creates a constant union node if we are doing a zero slot
scan on a partitioned table. However, if we are doing a zero slot scan on an
unpartitioned table, the planner creates a scan node. It would be correct to
create a constant union node in both cases.
