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

             Summary: TestRegionPlacement is failing undeterministically
                 Key: HBASE-12149
                 URL: https://issues.apache.org/jira/browse/HBASE-12149
             Project: HBase
          Issue Type: Bug
          Components: test
    Affects Versions: 1.0.0
            Reporter: Manukranth Kolloju
            Assignee: Manukranth Kolloju
            Priority: Minor
             Fix For: 1.0.0


TestRegionPlacement has tests that are flaky and fail in a cascading fashion. We need to fix
this cascading behavior and also fix the flakyness of the tests.
