["Amruta Borkar (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/AMBARI-16170?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Amruta Borkar updated AMBARI-16170:
-----------------------------------
    Attachment: Ambari-16170.patch

Created a patch to export path properties as references, which will be replaced if user modifies them in blueprint or adds in blueprint template, otherwise those will get replaced by Ambari default values.
Tested the patch by exporting a blueprint and deploying a cluster.

> Replace the some default paths by references, when a blueprint is exported. 
> Ex. Log dir, 
>       pid dir, 
>       tmp dir
> After creating references for paths, customizing cluster configuration would become easier, keeping an option open for having default configuration. 
> References that Ambari can assume default values for if found to not have been replaced in the blueprint or cluster template.
