-----------------------------------
Summary: Integrate with Spark OutputMetrics
Key: HIVE-18690
URL: https://issues.apache.org/jira/browse/HIVE-18690
Project: Hive
Issue Type: Sub-task
Components: Spark
Reporter: Sahil Takiar
Spark has an {{OutputMetrics}} it uses to expose records / bytes written. We
currently don't integrate with it and the Spark UI shows a blank value for
output records / bytes. We have our own customer accumulators instead (like
{{HIVE_RECORDS_OUT}}).
Spark exposes the {{OutputMetrics}} object inside individual tasks via the
{{TaskContext.get()}} method. We can use this method to access the
{{OutputMetrics}} object and update it.
