Gracefully shut down an HBase RegionServer

You can gracefully shut down an HBase RegionServer using Cloudera Manager.

  1. In Cloudera Manager, select the HBase service.
  2. Click the Instance tab.
  3. From the list of Role Instances, select the RegionServer or RegionServers you want to shut down gracefully.
  4. Click Actions for Selected.
  5. Select Decommission (Graceful Stop).
    If you cancel the graceful shutdown before the Graceful Shutdown Timeout expires, you can still manually stop a RegionServer by selecting Actions for Selected > Stop, which sends a SIGTERM (kill -15) signal.
