-------------------------------------
Summary: CostingSegment.java is initialized with wrong cost
Key: IMPALA-13119
URL: https://issues.apache.org/jira/browse/IMPALA-13119
Project: IMPALA
Issue Type: Bug
Components: Frontend
Affects Versions: Impala 4.4.0
Reporter: Riza Suminto
Assignee: Riza Suminto
CostingSegment.java has two public constructor: one accept PlanNode, while the
other accept DataSink as parameter. Both call appendCost method, which sum the
additionalCost with the segment's current cost_.
However, if cost_ were ProcessingCost.zero(), it can mistakenly
setNumRowToConsume to 0.
[https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/planner/CostingSegment.java#L114]
The public constructor should just initialize cost_ with ProcessingCost from
PlanNode or DataSink from constructor.
