Vijay Srinivasaraghavan updated AMBARI-13134:
---------------------------------------------
Description:
Stack advisor provides service component placement recommendations for any
given set oif hosts and services with the assumption that all the hosts are
homogeneous (same configuration - cpu/memory). This limits the possibility of
assigning hosts that are capable of being master to associate master service
components.
By passing the host-group information with some hints specifying which
distinction between master and slave nodes, the stack advisor component could
place the appropriate master service components with the associated master
hosts.
Stack advisor could parse the host group name ("masters" vs "slaves" vs
"clients") and identifies if the hosts could be treated as master or slave. In
the absence of the "hint", all the hosts will be assumed to be homogeneous
(default/current implementation)
