[jira] [Updated] (KNOX-1266) Support aliases for default discovery
address and cluster name
[ https://issues.apache.org/jira/browse/KNOX-1266?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Phil Zampino updated KNOX-1266:
-------------------------------
Description:
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.
