The node that the project will be deployed on should have the same
configuration as the cluster, and hadoop executables as well. It doesn't
have to be one of the cluster nodes.
This node is typically called a gateway or edge node, where it have all
the client programs (hadoop execs, pig, etc...) and you use this node to
submit jobs to the cluster.
The executable use the configuration to know where to submit jobs and
where is your hdfs nn located and so on.

Does you mean that the program must be deployed on any node of the
cluster?
I have some experience in operating database, I can
query/edit/add/remove data on the OS witch the database installed on,
or operate from the other machine remotely. Can I use Hadoop remotely
as to use database in a similar way?

sorted, But u can use this for debuging
