HBase runs off the road if you enable/disable/enable/disable the table and then delete
--------------------------------------------------------------------------------------

                 Key: HBASE-3077
                 URL: https://issues.apache.org/jira/browse/HBASE-3077
             Project: HBase
          Issue Type: Bug
            Reporter: stack


HBASE-3063 has a bit of detail.  The new master is better around disable, delete but still
not good enough.  This issue is about digging in a bit.  While disable and enable are not
just flags up in zk, setting either is followed by the actual open/close of regions.  We need
to add support to the master where it can follow swift enabling/disabling.  HBASE-3063 add
some lag to the delete so we'll wait on region close before we go ahead and remove the region
but we should be able to do better here too... e.g.  make use of Nicolas's new interrupt compactions
so delete doesn't ahve to wait on ongoing compactions... and we could add an abort of specific
regions only so we could  just crash them closed rather than wait on flushes if they are going
to be just deleted anyways.
