[jira] [Created] (HBASE-24292) A "stuck" master should not idle as active without taking action

Nick Dimiduk created HBASE-24292:
------------------------------------

             Summary: A "stuck" master should not idle as active without taking action
                 Key: HBASE-24292
                 URL: https://issues.apache.org/jira/browse/HBASE-24292
             Project: HBase
          Issue Type: Bug
          Components: master, Region Assignment
    Affects Versions: 2.3.0
            Reporter: Nick Dimiduk


The master schedules a SCP for the region server hosting meta. However, due to a misconfiguration, the cluster cannot make progress. After fixing the configuration issue and restarting, the cluster still cannot make progress. After the configured period (15 minuets), the master enters a "holding pattern" where it retains Active master status, but isn't taking any action.

This "brown-out" state is toxic. It should either keep trying to make progress, or it should abort. Staying up and not doing anything is the wrong thing to do.
