Description

If you try to unset a deprecated property in an CapacitySchedulerConfiguration object the value wont be removed.

Example failing Test for the TestCapacitySchedulerConfiguration class

@Test
public void testDeprecationFeatureWorks() {
  final String value = "VALUE";
  final String goodName = "koko";
  final String depName = "dfs.nfs.exports.allowed.hosts";
  final CapacitySchedulerConfiguration csConf = createDefaultCsConf();

  csConf.set(goodName, value);
  csConf.unset(goodName);
  assertNull(csConf.get(goodName));

  csConf.set(depName, value);
  csConf.unset(depName);
  assertNull(csConf.get(depName));  // fails here
}
