[jira] [Created] (HBASE-23262) Cannot load Master UI
Karthik Palanisamy created HBASE-23262:
------------------------------------------
Summary: Cannot load Master UI
Key: HBASE-23262
URL: https://issues.apache.org/jira/browse/HBASE-23262
Project: HBase
Issue Type: Bug
Components: master, UI
Affects Versions: 3.0.0
Reporter: Karthik Palanisamy
Assignee: Karthik Palanisamy
If no online regionservers then master UI can't be opened. This issue occurs when using RSGroupAdminEndpoint coprocessor(RSGrouping). The master home page tries to load rsgroup info from "hbase:rsgroup" table but currently no regionservers up and running.
