How to start a datanode?

One of my datanode is stop
Can I start the datanode and add it to the cluster without restarting the
hole cluster?

Hi,

You can use the hadoop-deamon script to control specific hadoop processes on
specific machines:
hadoop-daemon.sh start datanode

With the right configuration the datanode will join the working cluster just
like any other node.
