Hyukjin Kwon commented on SPARK-38682:
--------------------------------------
I think it's best to describe how to reproduce this problem. one workaround
should be to increase the memory size of dirver.
> Complex calculations with lead to driver oom

> My spark job is working fine in version 3.0.1. After I upgraded to 3.2, the
> driver would hang during runtime due to oom. The dump file shows that the
> stageMetrics in SQLAppStatusListener are taking up a lot of memory.I'm
> wondering if it's related to the SPARK-33016 change, or if the execution plan
> change has created more tasks, causing the driver to run out of memory, or
> some other reason.
