             Summary: Add an option to reject multi-cf bulkloads
                 Key: HBASE-27376
                 URL: https://issues.apache.org/jira/browse/HBASE-27376
             Project: HBase
          Issue Type: New Feature
            Reporter: Bryan Beaudreault


Doing a multi-cf bulkload requires taking a write lock on the region. When 
bulkloading many regions or doing many bulkloads to individual regions, this 
can cause a sort of denial of service for the region or entire table.

For those deployments which prefer to prioritize uptime, we should provide the 
ability to disallow these multi-cf bulkloads. It would be good to make this 
configurable via hbase-site.xml and overridden by TableDescriptor.
