----------------------------------
Summary: Support aliases for default discovery address and cluster
name
Key: KNOX-1266
URL: https://issues.apache.org/jira/browse/KNOX-1266
Project: Apache Knox
Issue Type: Bug
Components: Server
Affects Versions: 1.1.0
Reporter: Phil Zampino
Currently, service discovery requires 4 pieces of information to interact with
Ambari to generate topologies from descriptors:
* discovery address
* discovery cluster
* discovery username
* discovery password alias
At present, there are 2 well-known aliases, which serve to provide defaults if
the corresponding details aren't specified in a descriptor:
* ambari.discovery.user - The value of this alias is the username for
authenticating with the discovery source
* ambari.discovery.password - The value of this alias is the password
corresponding to the discovery user
This issue suggests that Knox could support aliases as defaults for the
remaining 2 discovery properties:
* ambari.discovery.address
* ambari.discovery.cluster
This would make it easier for users who are defining multiple descriptors for
the same cluster. The discovery details could be omitted from the descriptors,
such that the defaults defined as aliases would be used.
