I see, regarding the memory part, it sounds like we could do it in bash,
but it might be kind of painful. We could do the following:
- Look for just the driver memory and cluster mode arguments using bash
- If we're not running in cluster mode, set the -Xmx and -Xms parameters
when launching
I agree that we shouldn't use the full memory you required if you submitted
to a cluster. I'm not sure how hard it is to parse these arguments in bash --
it shouldn't be *that* hard, but we'll also have to do it in .cmd scripts on
Windows and such. Otherwise It would be good to test how slow this is with two
JVM launches (maybe we can avoid a lot of the slowness).
