Package org.apache.hadoop.hbase.master.balancer

Class TestRegionsOnMasterOptions

java.lang.Object

org.apache.hadoop.hbase.master.balancer.TestRegionsOnMasterOptions

public class TestRegionsOnMasterOptions
extends Object

Test options for regions on master; none, system, or any (i.e. master is like any other regionserver). Checks how regions are deployed when each of the options are enabled. It then does kill combinations to make sure the distribution is more than just for startup. NOTE: Regions on Master does not work well. See HBASE-19828. Until addressed, disabling this test.
