This is for the Solr package ... My goal is to expose the ZooKeeper
connection string used by SolrCloud in the registry so client
applications can look it up dynamically. Thus, in my metainfo.xml, I
have the following:
<exportGroups>
<exportGroup>
<name>Servers</name>
<exports>
<export>
<name>host_port</name>
<value>http://${SOLR_HOST}:${site.global.listen_port}/</value>
</export>
<export>
<name>zkhost</name>
<value>${site.global.zk_host}</value>
</export>
</exports>
</exportGroup>
</exportGroups>
<components>
<component>
<name>SOLR</name>
<category>SLAVE</category>
<compExports>Servers-host_port,Servers-zkhost</compExports>
<commandScript>
<script>scripts/solr_node.py</script>
<scriptType>PYTHON</scriptType>
</commandScript>
</component>
</components>
In the slider.log, I see:

When I run the registry command for Solr, I only get the host_port
values, but not the ZooKeeper setting ... the only thing I can think
of is it is the same value for all SOLR components. Here's the output
from the registry command:
[~/dev/lw/projects/incubator-slider/slider-assembly/target/slider-0.81.0-incubating-SNAPSHOT]$

}
This is with the latest develop branch.
