-----------------------------------------------------------------
Thanks for the patch & raising the issue for discussion [~bibinchundatt].
IMHO, i would suggest to have it as host name itself, it will be uniform
everywhere both while setting and fetching attributes. I was initially thinking
of having an overloaded method for scheduler perse but later changed my mind
and thinking of having some helpers inside scheduler to fetch the attributes
from the manager based on NodeId which internally can call manager's api
passing the hostname.
As well in the current code we are only storing the Node's Hostname in the
Manager and hence it would not be ideal to return NodeId with port always as
*"0"*.
