Description
Today, if a user happens to do something like a large multi-put, they can get through request throttling (e.g. it is one request) but still crash a region server with a garbage storm. We have seen regionservers hit this issue and it is silent and deadly. The RS will report nothing more than a mysterious garbage collection and exit out.
Ideally, we could report a large multi-* request before starting it, in case it happens to be deadly. Knowing the client, user and how many rows are affected would be a good start to tracking down painful users.
