--------------------------------------------
Summary: Deflake TestRSGroupsBasics#testClearDeadServers
Key: HBASE-24480
URL: https://issues.apache.org/jira/browse/HBASE-24480
Project: HBase
Issue Type: Bug
Components: rsgroup
Affects Versions: 2.3.0, 1.7.0
Reporter: Bharath Vissapragada
Assignee: Bharath Vissapragada
Ran into this on our internal forks based on branch-1. It also applies to
branch-2 but not master because the code has been re-implemented without
co-proc due to HBASE-22514
Running into this exception in the test run..
