I am trying to train a large dataset consisting of 8 million data points and
20 million features using SVMWithSGD. But it is failing after running for
some time. I tried increasing num-partitions, driver-memory,
executor-memory, driver-max-resultSize. Also I tried by reducing the size of
dataset from 8 million to 25K (keeping number of features same 20 M). But
after using the entire 64GB driver memory for 20 to 30 min it failed.
I'm using a cluster of 8 nodes (each with 8 cores and 64G RAM).
executor-memory - 60G
driver-memory - 60G
num-executors - 64
And other default settings
This is the error log :
