> - At present hooks are located inside stacks
> - For all HDP stacks, we use
> https://github.com/apache/ambari/tree/trunk/ambari-server/src/main/resources/stacks/HDP/2.0.6/hooks
> - Similarly for all HDF stacks, we use
> https://github.com/apache/ambari/tree/trunk/contrib/management-packs/hdf-ambari-mpack/src/main/resources/stacks/HDF/2.0/hooks
> - Any time the HDP hooks are updated, the changes have to be ported to HDF
> branch. This is a maintenance overhead
> - In Ambari 3.0 when we move to mpack based operations model, this will be a
> maint nightmare.
> *Requirements*
> # We should look into making hooks stack agnostic.
> # Hooks should be moved from resources/stacks/HDP/2.0.6/hooks to
> resources/stack-hooks
> # Hooks should be entirely config driven
> # There should be no HDP or HDF specific logic in the hooks (hdp-select,
> conf-select, hdf-select, hdfconf-select)
> # There should be no service specific logic in the hooks (for example:
> hardcoded service user to service group mapping etc. this should be stack
> driven see: AMBARI-20034).
> # Any service specific logic that doesn't make sense should be removed and
> refactored into respective service definitions.
