Resolution: Fixed
> Support aliases for default discovery address and cluster name
> --------------------------------------------------------------
>
> Key: KNOX-1301
> URL: https://issues.apache.org/jira/browse/KNOX-1301
> Project: Apache Knox
> Issue Type: Bug
> Components: Server
> Affects Versions: 1.1.0
> Reporter: Phil Zampino
> Assignee: Phil Zampino
> Priority: Major
> Fix For: 1.1.0
>
>
> Ambari service discovery should support aliases for defining the default
> discovery address and cluster name.
> Some admins would like to be able to omit these details from descriptors when
> most of the descriptors will reference the same Ambari cluster.
> With the remote alias service, Knox HA deployments are able to manage such
> aliases more consistently.
> The new aliases will be named:
> * ambari.discovery.address - The default Ambari discovery address
> * ambari.discovery.cluster - The default Ambari cluster name
> The naming convention follows the pattern of the existing
> ambari.discovery.user and ambari.discovery.password aliases.
> If these aliases are defined, and the corresponding properties are not
> specified in a descriptor, the values of these aliases will be used as
> defaults.
> If either of these aliases is NOT defined, and is also unspecified in a
> descriptor, then discovery shall not be attempted.
> The Admin UI must also be addressed as part of this, since there is currently
> some validation to ensure that a sufficient amount of discovery information
> is specified in a new descriptor (if any is specified at all).
