Subject [jira] [Created] (AMBARI-1269) Refactor ResourceProvider SPI

-------------------------------------

             Summary: Refactor ResourceProvider SPI
                 Key: AMBARI-1269
                 URL: https://issues.apache.org/jira/browse/AMBARI-1269
             Project: Ambari
          Issue Type: Bug
            Reporter: Tom Beerbower
            Assignee: Tom Beerbower


Refactor the SPI for resource providers for the following ...

  * Remove getProperties() from ResourceProvider and PropertyProvider.  Some providers are
not able to give a complete list of supported properties since the list may actually be dynamic.
  * Allow for Map type properties to be accessed as if they were categories.  For example
the following request ...
{code}
 ...services/HDFS/?fields=ServiceInfo/desired_configs/global
{code}
... gets the global value from desired_configs category where desired_configs is actually
a Map type property and global is the key to one of its entries.
  * Move common code for dealing with property manipulation in a provider into internal base
classes.
