Description
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.
