--------------------------------

             Summary: HBase RegionServer Canary reports failure if an online regionserver is hosting 0 regions
                 Key: HBASE-25730
                 URL: https://issues.apache.org/jira/browse/HBASE-25730
             Project: HBase
          Issue Type: Bug
          Components: canary
            Reporter: Caroline
            Assignee: Caroline


The probability of this happening increases with system rsgroup enabled (i.e. an rsgroup dedicated to system tables, which have few regions) and paired with table-level load balancing. As long as the server is alive and able to accept/serve regions, we should not consider it an error case if it is currently serving no regions.
