             Summary: Provide administrative limits around bulkloads of files into a single region
                 Key: HBASE-7849
                 URL: https://issues.apache.org/jira/browse/HBASE-7849
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: Harsh J


Given the current mechanism, it is possible for users to flood a single region with 1k+ store files via the bulkload API and basically causes 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.
