spark.executor.memory ? is used just for cache RDD or both cache RDD and the runtime of cores on worker?

[charles li]

if set spark.executor.memory = 2G for each worker [ 10 in total ]

does it mean I can cache 20G RDD in memory ? if so, how about the memory
for code running in each process on each worker?

thanks.

and is there any materials about memory management or resource management
in spark ? I want to put spark in production, but have little knowing about
the resource management in spark, great thanks again

You would probably like to see
http://spark.apache.org/docs/latest/configuration.html#memory-management.
Other config parameters are also explained there.
