---------------------------------------------------
Summary: 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
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.
