Description

Currently, both the stack-select and conf-select python files have hard-coded structures inside of them which contain mappings for things like configuration directories and stack-select component names.

This code is really HDP-specific in that it reverses the mappings of the RPMs and allows us to remap /etc/<component>/conf to /usr/hdp/current/<stack-component>/conf

conf_select.py

_PACKAGE_DIRS = {
  "atlas": [
    {
      "conf_dir": "/etc/atlas/conf",
      "current_dir": "{0}/current/atlas-client/conf".format(STACK_ROOT_PATTERN)
    }
  ],
  "accumulo": [
    {
      "conf_dir": "/etc/accumulo/conf",
      "current_dir": "{0}/current/accumulo-client/conf".format(STACK_ROOT_PATTERN)
    }
  ],
...

With the coming of management packs replacing stacks, we can no longer hard code this in Python. My suggestion is to begin moving this data into a property of some sort. Today, cluster-env exists and would be the only place for it (where the stack-feature tools are now). However, I believe that cluster-env is also going away and being replaced with something similar to "Cluster Settings".

In any event, this Jira is to track the work needed to replace this logic.
