Adding AMPS to existing system

Dear all,

Does Hash map change when additional AMPs are added?
if yes , does existing data goes under redistribution?

Does all the data that exists in the warehouse undergoes redistrubution every time you are adding resources to your system ?

what happens to existing appliations/programs which are accessing the databases?

Does this addion of resources is offline acticity? Does it require the downtime of the system?
