Apache Spark reassigned SPARK-42252:
------------------------------------
Assignee: (was: Apache Spark)
> Deprecate spark.shuffle.unsafe.file.output.buffer and add a new config
> ----------------------------------------------------------------------
>
> Key: SPARK-42252
> URL: https://issues.apache.org/jira/browse/SPARK-42252
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.0.0
> Reporter: Wei Guo
> Priority: Minor
> Fix For: 3.4.0
>
>
> After Jira SPARK-28209 and PR
> [25007|[https://github.com/apache/spark/pull/25007]], the new shuffle writer
> api is proposed. All shuffle writers(BypassMergeSortShuffleWriter,
> SortShuffleWriter, UnsafeShuffleWriter) are based on
> LocalDiskShuffleMapOutputWriter to write local disk shuffle files. The config
> spark.shuffle.unsafe.file.output.buffer used in
> LocalDiskShuffleMapOutputWriter was only used in UnsafeShuffleWriter before.
>
> It's better to rename it and make it more suitable.
