---------------------------------------

             Summary: VisibilityController returns the wrong value for preBalanceSwitch()
                 Key: HBASE-11755
                 URL: https://issues.apache.org/jira/browse/HBASE-11755
             Project: HBase
          Issue Type: Bug
          Components: Coprocessors
    Affects Versions: 0.98.5, 1.0.0, 2.0.0
            Reporter: Matteo Bertozzi
            Assignee: Matteo Bertozzi
            Priority: Minor
             Fix For: 1.0.0, 2.0.0, 0.98.6
         Attachments: HBASE-11755-v0.patch

VisibilityController returns false instead of the newValue for the preBalanceSwitch() call.

VisibilityController extends both RegionObserver and MasterObserver, unfortunately only 1
of the two can use the Base implementation. in this case the BaseRegionObserver is used and
all most of the MasterObserver methods are a noop. Any idea on how to avoid reimplementing
all the  interface methods as noop, and avoid problems like the preBalanceSwitch()?
