Description

Added dependency related information to stacks in the REST API. This information describes dependencies between components which are part of a stack.

A new dependencies resources will be added as a child to the stacksServices/serviceComponent (soon to be renamed to services/component) resource.

For example:
GET http://172.18.192.3:8080/api/v1/stacks/HDP/versions/1.3.3/stackServices/HBASE/serviceComponents/HBASE_MASTER?fields=dependencies/*

{
  "href" : "http://172.18.192.3:8080/api/v1/stacks/HDP/versions/1.3.3/stackServices/HBASE/serviceComponents/HBASE_MASTER?fields=dependencies/*",
  "StackServiceComponents" : {
    "component_name" : "HBASE_MASTER",
    "service_name" : "HBASE",
    "stack_name" : "HDP",
    "stack_version" : "1.3.3"
  },
  "dependencies" : [
    {
      "href" : "http://172.18.192.3:8080/api/v1/stacks/HDP/versions/1.3.3/stackServices/HBASE/serviceComponents/HBASE_MASTER/dependencies/HDFS_CLIENT",
      "Dependencies" : {
        "component_name" : "HDFS_CLIENT",
        "dependent_component_name" : "HBASE_MASTER",
        "dependent_service_name" : "HBASE",
        "scope" : "host",
        "service_name" : "HDFS",
        "stack_name" : "HDP",
        "stack_version" : "1.3.3"
      },
      "auto_deploy" : {
        "enabled" : true
      }
    },
    {
      "href" : "http://172.18.192.3:8080/api/v1/stacks/HDP/versions/1.3.3/stackServices/HBASE/serviceComponents/HBASE_MASTER/dependencies/ZOOKEEPER_SERVER",
      "Dependencies" : {
        "component_name" : "ZOOKEEPER_SERVER",
        "dependent_component_name" : "HBASE_MASTER",
        "dependent_service_name" : "HBASE",
        "scope" : "cluster",
        "service_name" : "ZOOKEEPER",

    }
