> Now in every datanode,concurrent xceivers count value are all set by
> {{DFSConfigKeys.DFS_DATANODE_MAX_RECEIVER_THREADS_DEFAULT}}.And if you want
> to set this value for different values because some node has lower memory or
> cores.Then you must to change the config and restart datanode.So may be we
> can dynamic set dataxceiver count by a dfsadmin command and we can set value
> for one or many specific nodes.
