Nicolas Spiegelberg commented on HBASE-3603:
--------------------------------------------
We're one of those wierdos, can we add this feature back in, but comment it
out? I think it's good to have a recommended list of optional features to play
with and then explain why they're disabled for the common use case.
> Remove -XX:+HeapDumpOnOutOfMemoryError autodump of heap option on OOME

> By default the -XX:+HeapDumpOnOutOfMemoryError option is set for HBase.
> Means we'll dump heap when we OOME. In the heaps we run with 8G, 16G, etc.,
> these can make for hefty files. No one really looks at these things other
> than a few weirdos and even then, the interesting ones are too big to ship
> easily. Meantime, they can cause headache. E.g. you are on EC2, root is but
> a small partition, and you set up hbase on root partition... a heap dump
> could cause your root partition to fill and make the machine unapproachable.
