Hi,

 

How did you infer from this image that driver memory would be 21.4 GB? Shouldn't it be 10.4 GB?

 

Also, if a memory is allocated to JVM related activities, can this memory can be also utilized from python? Meaning if I have 21.4 gb for JVM, does it mean I can use all that memory from python (for instance to load some crazdy pandas dataframes)?
