comment Running spark 1.2.0 on ec2?
@NickChammas - thanks, I was afraid this is the case, I'll fork the mesos install script and add my own rc2 pre-built instance as building this from source on each of the nodes is not practical :)

comment How do I see my git remote url?
Thanks, I was wondering if there is a non command line option within Intellij IDEA to do so. p.s. isn't that git remote show origin?

comment Can an array be larger than physical memory? (e.g. can it be partially paged)
Agree about the risk of thrashing. My requirement is merely the ability to iterate a large array (I'm forced by the API to use it) which only works on one item at a time. ideally an iterator would have been better, but I'm relying on the OS / JVM to "lazy load" the data from disk since it's so big. so if I define a big enough heap, this might even work...

Ok, so to summarize, if your heap size is larger than physical memory, both the array itself might get paged (not sure if partially or not though) but if the array is referencing objects, then they can be paged as well. e.g. if the array is 1,000,000 referrences to some large objects, I might still be able to survive iterating over it even if the total size of them + the references is smaller than physical memory. right?

@SotiriosDelimanolis - well, good question, since I used Strings in the example, then I guess the answer is the referenced elements. which makes me realize, the actual strings can be probably paged since they the array is an array of references, right?

@Dima thanks, so this means the max heap size can be larger than phisical memory? (which kind of makes sense I guess. this is what virtual memory is for after all, right?)
