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

             Summary: entries, entry_labels and entry_descriptions should not be defined as a flat list
                 Key: AMBARI-10309
                 URL: https://issues.apache.org/jira/browse/AMBARI-10309
             Project: Ambari
          Issue Type: Task
          Components: ambari-server
    Affects Versions: 2.1.0
            Reporter: Myroslav Papirkovskyy
            Assignee: Myroslav Papirkovskyy
             Fix For: 2.1.0


Enhanced configs has to show lists and combos which have entries. Each entry can have a label and description. They should show up in the API as 
{code}

{
  "href" : "http://c6401:8080/api/v1/stacks/HDP/versions/2.2/services/HIVE/configurations/hive.exec.orc.default.compress",
  "StackConfigurations" : {
    "final" : "false",
    "property_depended_by" : [ ],
    "property_depends_on" : [ ],
    "property_description" : "Define the default compression codec for ORC file",
    "property_name" : "hive.exec.orc.default.compress",
    "property_type" : [ ],
    "property_value" : "ZLIB",
    "property_value_attributes" : {
      "type" : "value-list",
      "entries" : [
        "ZLIB",
        "SNAPPY"
      ],
      "entryLabels" : [
        "zlib Compression Library",
        "Snappy Compression Library"
      ]
    },
    "service_name" : "HIVE",
    "stack_name" : "HDP",
    "stack_version" : "2.2",
    "type" : "hive-site.xml"
  }
}
{code}

To give the above output, currently we define the config in stack as shown below. 
{code}
   <property>
     <name>hive.exec.orc.default.compress</name>
     <value>ZLIB</value>
     <description>Define the default compression codec for ORC file</description>
    <display-name>ORC Compression Algorithm</display-name>
    <value-attributes>
      <type>value-list</type>
      <entries>ZLIB</entries>
      <entries>SNAPPY</entries>
      <entry_labels>zlib Compression Library</entry_labels>
      <entry_labels>Snappy Compression Library</entry_labels>
      <selection-cardinality>1</selection-cardinality>
    </value-attributes>
   </property>
{code}

The problem is that there is no containment for the entry, its label and its description. Due to this, there is not structure/correlation - which might cause issues. This has to change so that in the stack-definition it will be like
{code}
   <property>
     <name>hive.exec.orc.default.compress</name>
     <value>ZLIB</value>
     <description>Define the default compression codec for ORC file</description>
    <display-name>ORC Compression Algorithm</display-name>
    <value-attributes>
      <type>value-list</type>
      <entries>
        <entry>
          <value>ZLIB</value>
          <label>zlib Compression Library</label>
          <description>...</description>
        </entry>
        <entry>
          <value>SNAPPY</value>
          <label>Snappy Compression Library</label>
          <description>...</description>
        </entry>
      <entries>
      <selection-cardinality>1</selection-cardinality>
    </value-attributes>
   </property>
{code}

Labels and descriptions are optional.
