             Summary: Ambari Views auto create instance should support matching to all known stacks
                 Key: AMBARI-24059
                 URL: https://issues.apache.org/jira/browse/AMBARI-24059
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.6.0
            Reporter: Robert Nettleton
            Assignee: Robert Nettleton
             Fix For: 2.7.0


The Ambari Views framework currently defines a set of configuration tags that can be used to configure the auto-instance deployment of a view.  Currently, this configuration allows for a matching stack to be explicitly configured, or a wildcard ('*") can be used to allow more flexible matching against a set of stack version numbers. 

The current configuration already supports this type of matching: 

 
{code:java}
<auto-instance>
<name>AUTO_INSTANCE</name>
<label>View Name</label>
<stack-id>HDP-*</stack-id>
:
</auto-instance>{code}
This configuration needs to be more flexible in order to allow a given View implementation to specify that it can match to any stack, including those defined outside of the "HDP" stack name. 

The Ambari Views Registry should be updated to allow for specifying a wilcard character in order to instruct the Views framework to match against any stack, regardless of whether the stack begins with the "HDP" stack name. 
{code:java}
<auto-instance>
<name>AUTO_INSTANCE</name>
<label>View Name</label>
<stack-id>*</stack-id>
:
</auto-instance>{code}
This change should allow for greater flexibility for service and view developers, in cases where a given service's view can be used by more than one stack.
