installation - hadoop install on round-robin DNS -

-

i want install hadoop on round-robin dns environment. have bunch of machines sharing common user environment , common name. these machines equal. round-robin dns runs on branch of machines. each machine has own ip address , host name. our school's machines. these machines share common name. when login, terminal shows machine on.

the problem make change on 1 machine, changes applies other machines.

i follow instruction of michael-noll's multi-node hadoop. need configure master node. did master node applies slave nodes. said, cannot differentiate master , slave nodes.

so, can install hadoop in such environment?

i'm not quite sure why want install hadoop using round-robin dns, no, cannot hadoop. every single node needs have unique host name.
