------------------------------------
Assignee: (was: Apache Spark)
> Adaptive fetch of shuffle mergers for Push based shuffle
> --------------------------------------------------------
>
> Key: SPARK-34826
> URL: https://issues.apache.org/jira/browse/SPARK-34826
> Project: Spark
> Issue Type: Sub-task
> Components: Shuffle, Spark Core
> Affects Versions: 3.1.0
> Reporter: Venkata krishnan Sowrirajan
> Priority: Major
>
> Currently the shuffle mergers are set during the creation of ShuffleMapStage.
> In the initial set of stages, there won't be enough executors added which can
> cause not enough shuffle mergers to be set during the creation of the shuffle
> map stage. This task is to handle the issue of low merge ratio for initial
> stages.
