----------------------------------------
Summary: Replace Hard Coded conf-select Structures
Key: AMBARI-21581
URL: https://issues.apache.org/jira/browse/AMBARI-21581
Project: Ambari
Issue Type: Task
Affects Versions: 2.5.3
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Priority: Critical
Fix For: 2.5.3
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}}
{code:title=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)
}
],
...
{code}
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.
