> Key: TEZ-2962
> URL: https://issues.apache.org/jira/browse/TEZ-2962
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Bikas Saha
> Priority: Critical
>
> The original code used output size sent by completed tasks. Recently per
> partition stats have been added that provide granular information. Using
> partition stats may be more accurate and also remove the duplicate counting
> of data size in partition stats and per task overall.
