      Description

      In discussing ACCUMULO-4166 with Keith Turner, we decided that the underlying issue is that major compactions can overwhelm a tablet server, rendering it nearly unresponsive.

      To address this, we should take a cue from Apache Cassandra and restrict how quickly we perform major compactions. Rate limiting reads and writes involved in major compactions will directly affect the IO load caused by major compactions, and should also indirectly affect the CPU load.
