----------------------------

             Summary: Lazy computing in HiveBaseFunctionResultList may hurt performance [Spark
Branch]
                 Key: HIVE-9574
                 URL: https://issues.apache.org/jira/browse/HIVE-9574
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Rui Li


{{RowContainer.first}} may call {{InputFormat.getSplits}}, which is expensive. If we switch
{{container}} and {{backupContainer}} frequently in {{HiveKVResultCache}}, it will downgrade
performance.
