[jira] [Created] (HBASE-8801) Region level read/write degradation

Chao Shi created HBASE-8801:
-------------------------------

             Summary: Region level read/write degradation
                 Key: HBASE-8801
                 URL: https://issues.apache.org/jira/browse/HBASE-8801
             Project: HBase
          Issue Type: Bug
            Reporter: Chao Shi


We would like to propose a tool for HBase administrators to disable read and/or write for single region temporarily.

Our HBase table at weibo.com is accessed by many clients. We have experienced the following outage: due to bugs of user code, a small number of regions are reading at very high rate. Requests to other regions at the same RSs are affected. In such scenario, the admin would like to temporarily set the region to write-only (only forbids reads so writes can still being served).
