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. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
