Gour Saha commented on SLIDER-1064:
-----------------------------------
Absolutely. I was just trying to say why we did not do it and some of the
things we have to keep in mind to design it right. Maybe this bug deserves to
be changed to an improvement right away.

> 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
> {code:xml}

> 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",
