Dongjoon Hyun updated SPARK-26679:
----------------------------------
Affects Version/s: (was: 2.4.0)
3.0.0
> Deconflict spark.executor.pyspark.memory and spark.python.worker.memory
> -----------------------------------------------------------------------
>
> Key: SPARK-26679
> URL: https://issues.apache.org/jira/browse/SPARK-26679
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 3.0.0
> Reporter: Ryan Blue
> Priority: Major
>
> In 2.4.0, spark.executor.pyspark.memory was added to limit the total memory
> space of a python worker. There is another RDD setting,
> spark.python.worker.memory that controls when Spark decides to spill data to
> disk. These are currently similar, but not related to one another.
> PySpark should probably use spark.executor.pyspark.memory to limit or default
> the setting of spark.python.worker.memory because the latter property
> controls spilling and should be lower than the total memory limit. Renaming
> spark.python.worker.memory would also help clarity because it sounds like it
> should control the limit, but is more like the JVM setting
> spark.memory.fraction.
