| <<-EOF |
| Enable exceed throttle quota. Returns previous exceed throttle quota enabled value. |
| NOTE: if quota is not enabled, this will not work and always return false. |
| |
| If enabled, allow requests exceed user/table/namespace throttle quotas when region |
| server has available quota. |
| |
| There are two limits if enable exceed throttle quota. First, please set region server |
| quota. Second, please make sure that all region server throttle quotas are in seconds |
| time unit, because once previous requests exceed their quota and consume region server |
| quota, quota in other time units may be refilled in a long time, which may affect later |
| requests. |

| Examples: |
| hbase> enable_exceed_throttle_quota |
| EOF |
