The administrator should be able to specify a list of data nodes > in a file similar to the hosts file and the balancer should ignore these data > nodes while balancing so that no blocks are added/removed on these nodes. > Similarly it will be beneficial to specify that only a particular list of > datanodes should be considered for balancing. -- This message was sent by Atlassian JIRA (v6.2#6252)
