org.apache.hadoop.hbase.master

Class TestMasterBalancerNPE.MyLoadBalancer

java.lang.Object

org.apache.hadoop.hbase.master.balancer.BaseLoadBalancer

org.apache.hadoop.hbase.master.balancer.StochasticLoadBalancer

org.apache.hadoop.hbase.master.TestMasterBalancerNPE.MyLoadBalancer

All Implemented Interfaces:

org.apache.hadoop.hbase.conf.ConfigurationObserver, org.apache.hadoop.hbase.master.LoadBalancer, org.apache.hadoop.hbase.Stoppable

Enclosing class:

TestMasterBalancerNPE

static class TestMasterBalancerNPE.MyLoadBalancer
extends org.apache.hadoop.hbase.master.balancer.StochasticLoadBalancer

Define this class because the test needs to override StochasticLoadBalancer.balanceTable(org.apache.hadoop.hbase.TableName, java.util.Map<org.apache.hadoop.hbase.ServerName, java.util.List<org.apache.hadoop.hbase.client.RegionInfo>>), which is protected.
