> During the first startup usually we need to wait about 30 s to find the scm 
> usable. The datanode registration is a multiple step process 
> (request/response + request/response) and we need to wait the next HB to 
> finish the registration.
> I propose to use a more higher HB frequency at startup (let's say 2 seconds) 
> and set the configured HB only at the end of the registration.
> It also helps for the first users as it could be less confusing (the datanode 
> can be seen almost immediately on the UI)
> Also it would help a lot for me during the testing (yes, I can decrease the 
> HB frequency but in that case it's harder the follow the later HBs)
