---------------------------
Summary: When we submit spark core tasks frequently, the submitted
nodes will have a lot of resource pressure
Key: SPARK-34406
URL: https://issues.apache.org/jira/browse/SPARK-34406
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 3.0.1
Reporter: hao
When we submit spark core tasks frequently, the submitted node will have a lot
of resource pressure, because spark will create a process instead of a thread
for each submitted task. In fact, there is a lot of resource consumption. When
the QPS of the submitted task is very high, the submission will fail due to
insufficient resources. I would like to ask how to optimize the amount of
resources consumed by spark core submission
