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

             Summary: Improve VisibilityController initialization sanity checks
                 Key: HBASE-11264
                 URL: https://issues.apache.org/jira/browse/HBASE-11264
             Project: HBase
          Issue Type: Improvement
            Reporter: Andrew Purtell
            Priority: Minor
             Fix For: 0.99.0, 0.98.4


When using the AccessController and VisibilityController together, it is important that the AC is placed first in the system coprocessor list. Otherwise the VisibilityController will fail to initialize in a completely opaque way:

When initializing the VisibilityController, test for impending failure and issue an informative message at ERROR log level.
