[ https://issues.apache.org/jira/browse/SPARK-27874?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dongjoon Hyun updated SPARK-27874:
----------------------------------
Priority: Minor (was: Major)
> ShuffleBlockFetchIterator can log information about per-block sizes
> -------------------------------------------------------------------
>
> Key: SPARK-27874
> URL: https://issues.apache.org/jira/browse/SPARK-27874
> Project: Spark
> Issue Type: Improvement
> Components: Shuffle, Spark Core
> Affects Versions: 3.0.0
> Reporter: Bjorn Jonsson
> Priority: Minor
>
> It can be beneficial for monitoring and debugging to know the size of the largest shuffle block (or some distribution of block sizes). The ShuffleBlockFetcherIterator currently logs the number of local & remote blocks and their total size (see SPARK-26697), but does not log any information about per-block sizes.
