Description

Slider 0.80 with secured cluster. Registry is enabled *** without *** security

Export is configured as follows

1. No application level export
2. Component level port allocated per container. In appConfig.json, *** "global" *** section
"site.global.user1.http_port": "${user1.ALLOCATED_PORT}

{PER_CONTAINER}

",
3. Each component exports its own host/port (slider allocated). metainfo.xml

          <components>
            <component>
                  <name>user1</name>
                  <category>MASTER</category>
                  <componentExports>
                     <componentExport>
                       <name>my_info</name>
                       <value>${THIS_HOST}:${user1.http_port}</value>
                    </componentExport>
                  </componentExports>
                  <commandScript>
                    <script>scripts/memcached.py</script>
                    <scriptType>PYTHON</scriptType>
                  </commandScript>
                </component>

At runtime,

in http://am-host:1025/ws/v1/slider/publisher/slider/componentinstancedata, the host:port info can be seen as expected
{"description":"ComponentInstanceData","updated":0,"entries":{"container_1452045276360_0005_01_000004.my_info":"host1:33786", ....

However, when I look at ZK data,
get /registry/users/foo/services/org-apache-slider/<appname>/components/container-1452045276360-0005-01-000004, I don't see the host:port info. It only shows
{
"type" : "JSONServiceRecord",
"description" : "user1",
"external" : [ ],
"internal" : [ ],
"yarn:id" : "container-1452045276360-0005-01-000004",
"yarn:persistence" : "container"
}
