> Currently the {{property_depended_by}} information for a stack-configuration is calculated automatically. This has to be changed so that the derived information can be got through a sub-resource called dependencies. This will contain the same information as the configuration does currently.
> So a GET to [http://c6401:8080/api/v1/stacks/HDP/versions/2.2/services/YARN/configurations/yarn.scheduler.maximum-allocation-mb/dependencies] will give
> {code}
> {
>     "property_depended_by" : [
>       {
>         "type" : "mapred-site",
>         "name" : "yarn.app.mapreduce.am.resource.mb"
>       },
>       {
>         "type" : "mapred-site",
>         "name" : "mapreduce.map.memory.mb"
>       },
>       {
>         "type" : "mapred-site",
>         "name" : "mapreduce.reduce.memory.mb"
>       }
>     ]
> }
> {code}
> Additionally there should be a single API to get all the configurations, and all their depended_by relationship sub-resources. Currently the UI calls: 
> {code}
> http://c6401:8080/api/v1/stacks/HDP/versions/2.3/services?StackServices/service_name.in(HDFS,MAPREDUCE2,YARN,TEZ,HIVE,HBASE,PIG,ZOOKEEPER)
> &fields=configurations/*,StackServices/config_types/*
> {code}
> We should have something very similar like
> {code}
> http://c6401:8080/api/v1/stacks/HDP/versions/2.3/services?StackServices/service_name.in(HDFS,MAPREDUCE2,YARN,TEZ,HIVE,HBASE,PIG,ZOOKEEPER)
> &fields=configurations/*,configurations/dependencies,StackServices/config_types/*
