Guoliang Sun created KYLIN-6019:
-----------------------------------

             Summary: The metrics data for the number of scanned rows in pushdown queries is lost
                 Key: KYLIN-6019
                 URL: https://issues.apache.org/jira/browse/KYLIN-6019
             Project: Kylin
          Issue Type: Bug
    Affects Versions: 5.0.0
            Reporter: Guoliang Sun


h3. Root Cause

The operator types for scanning data contained in the generated SparkPlan are not fully covered when calculating `scanRows` and `scanBytes`. In the current case, this is due to the lack of accumulation of metrics for `HiveTableScanExecTransformer`.
