[jira] [Created] (DRILL-2639) Panner bug -
RelOptPlanner.CannotPlanException
Khurram Faraaz created DRILL-2639:
-------------------------------------
Summary: Panner bug - RelOptPlanner.CannotPlanException
Key: DRILL-2639
URL: https://issues.apache.org/jira/browse/DRILL-2639
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 0.9.0
Environment: | 9d92b8e319f2d46e8659d903d355450e15946533 | DRILL-2580: Exit early from HashJoinBatch if build side is empty | 26.03.2015 @ 16:13:53 EDT | Unknown | 26.03.2015 @ 16:53:21 EDT |
Reporter: Khurram Faraaz
Assignee: Jinfeng Ni
Priority: Critical
Reporting this as a separate JIRA as this issue related to a bug in the planner. Performing aggregate on the output returned by Union All results in CannotPlanException. Note that the two inputs to Union All are casted to integer and hence the inputs from both legs are of the same datatype.
