In prod practise, it's time consuming and tiring to assign tables to their rsgroups for HBase admin by shell, especially in 1.x rsgroup client is IA.private, we could not even write some programs to do that.
And I'm here proposing a solution to do the automated rsgroup assignment by allowing running a shell in postCreateTable to determine which table should go to which rsgroup (way in branch-1 not master). The benefit is obvious, admin can determine or change at any time the mapping rule in script without restarting or re-config anything. It's flexible, convenience and time saving.
