             Summary: [hbck2] Simplification on HBCKSCP scheduling
                 Key: HBASE-23322
                 URL: https://issues.apache.org/jira/browse/HBASE-23322
             Project: HBase
          Issue Type: Sub-task
          Components: hbck2
            Reporter: Michael Stack
            Assignee: Michael Stack


I can make the scheduling of HBCKSCP simpler.  I can also fix a bug in parent issue that I notice after exercising it a bunch on a cluster.

The bug is that 'Unknown Servers' seem to be retained in the Map of reporting servers. They are usually cleared just before an SCP is scheduled but scheduling HBCKSCP doesn't go the usual route.

The patch here forces HBCKSCP via the usual SCP route only at the scheduling time, context dictates whether SCP or the scouring HBCKSCP.

Let me put up a patch and will test in meantime.
