[jira] [Updated] (SPARK-13007) Document where configuration / properties are read and applied

     [ https://issues.apache.org/jira/browse/SPARK-13007?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alan Braithwaite updated SPARK-13007:
-------------------------------------
    Description: 
While spark is well documented for the most part, often times I have trouble determining where a configuration applies.

For example, when setting spark.dynamicAllocation.enabled	, does it always apply to the entire cluster manager, or is it possible to configure it on a per-job level?

Different levels I can think of:
Application
Driver
Executor
Worker
Cluster

And I'm sure there are more.  This could be just another column in the configuration page.
