OutOfMemoryError: Java heap space - is it executor or driver?

[Nirav Patel <np...@xactlycorp.com>]

I hit OOM error at certain point. Mostly noticed after fitting model
multiple times. I can't figure out if this is driver or executor. From logs
it looks like Driver. I don't see any heap space error in Executor logs>
