Summary: Include planner-estimated host count in summary
Key: IMPALA-7303
URL: https://issues.apache.org/jira/browse/IMPALA-7303
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Affects Versions: Impala 2.12.0
Reporter: Balazs Jeszenszky
Currently, the host count included in the execution summary is a record of what
actually happened. The planner-estimated host count is visible only in the plan
itself. Summary should include an 'Est. #Hosts', like for the rest of the
values.
Plan:
{code:java}
F09:PLAN FRAGMENT [RANDOM] >>>>>hosts=1 instances=1<<<<<
| | Per-Host Resources: mem-estimate=1.75GB mem-reservation=1.94MB
| | 14:HASH JOIN [LEFT OUTER JOIN, BROADCAST]
{code}
Summary:
{code:java}
Operator #Hosts
14:HASH JOIN 105
{code}
