after some testing, the python driver memory is not limited by
spark.driver.memory
instead, there is no limit at all for those processes. This may be
managed by cgroups however.

pySpark driver memory limit

[Nicolas Paris]

hi there


Can anyone clarify the driver memory aspects of pySpark?
According to [1], spark.driver.memory limits JVM + python memory.

In case:
spark.driver.memory=2G
Then does it mean the user won't be able to use more than 2G, whatever
the python code + the RDD stuff he is using ?

Thanks,
