> Given the current mechanism, it is possible for users to flood a single 
> region with 1k+ store files via the bulkload API and basically cause the 
> region to become a flying dutchman - never getting assigned successfully 
> again.
> Ideally, an administrative limit could solve this. If the bulkload RPC call 
> can check if the region already has X store files, then it can reject the 
> request to add another and throw a failure at the client with an appropriate 
> message.
> This may be an intrusive change, but seems necessary in perfecting the gap 
> between devs and ops in managing a HBase clusters. This would especially 
> prevent abuse in form of unaware devs not pre-splitting tables before 
> bulkloading things in. Currently, this leads to ops pain, as the devs think 
> HBase has gone non-functional and begin complaining.
