> Support qualifying service params for CM discovery control
> ----------------------------------------------------------

> Key: KNOX-2530
> URL: https://issues.apache.org/jira/browse/KNOX-2530
> Project: Apache Knox
> Issue Type: Improvement
> Components: cm-discovery
> Affects Versions: 1.5.0
> Reporter: Philip Zampino
> Assignee: Philip Zampino
> Priority: Major
> Fix For: 1.6.0
>
> Time Spent: 1h
> Remaining Estimate: 0h

> Add support for discovery-only service params in descriptor service
> declarations, such that the ClouderaManager discovery process can be
> controlled for HA and other deployments where there are multiple sources of
> endpoint information that should not be combined for a given topology.
> One example is HDFS HA, where a nameservice can be specified. (Similar
> support for this exists for Ambari discovery)
> {noformat}

> "discovery-pwd-alias":"cm.discovery.pwd",

> "services":[
> {
> "name":"WEBHDFS",
> "params": {
> "discovery-nameservice":"ns2"
> }
> }
> ]
> }{noformat}
> Another example is a cluster with multiple SOLR instances.

> These discovery-only service parameters are prefixed with *discovery-*, and
> must not manifest in the generated topologies.
