For example when the cluster is extended,the new nodes all need balancer datas from existed nodes.In order to improve the balancer velocity,generally,we will use {{setBalancerBandwidth}} of {{dfsadmin}} command.But this is set for every node, obviously,we can increase more bandwidth for new nodes because these nodes lacking of data.When the new nodes balancer data enough,we can let new nodes to work.So we can define a new clientDatanode interface to set specific node's bandwidth. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
