--------------------------------
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.
