one node restart
Hi
When one of my node in cluster restart,would it be automatically added in
HDFS ?
When I restart one of my node,I have to restart the Hadoop. Is there any
solution for this?

Depends on the distribution you are using. Most of them have services around those services and will start automatically.
If not, it surely can be configured that way.

Hi
There is no need to restart entire cluster if just add a node. Unless there
is somethig specific added by the vendor.
It will be added to HDFS and jobtracker.

Serge
