             Summary: Views: Add <mask> optional attribute to <parameter> in view.xml
                 Key: AMBARI-6344
                 URL: https://issues.apache.org/jira/browse/AMBARI-6344
             Project: Ambari
          Issue Type: Task
          Components: controller
    Affects Versions: 1.7.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
             Fix For: 1.7.0
         Attachments: AMBARI-6344.patch

Certain parameters that ambari will persist should be optionally masked. This will be useful in cases where an instance parameter is a password or something similar. By having this setting available, Ambari can handle storing the parameter in a non-plain-text way, as well, the UI for configuring view instances will know to mask the parameter (input type=password). 

1. There should be a default masking implementation (can be something simple like base64 encode for example) that for a parameter that has the <mask> attribute, the parameter will be masked.

<parameter>
<mask>true</mask>
...
</parameter>

2. There is a more advanced option where a view also specifies the <mask-class> to customize the way parameters are read/written. The class (implements an interface, maybe) for callback on read/write of the parameter so view developers can implement a special way to encrypt/decrypt.

<mask-class>my.custom.class</mask-class>
<parameter>
<mask>true</mask>
...
</parameter>

Note: changing the terminology to mask (from encrypt) since encrypt sets a certain expectation. Masking in the default sense is good convenience to provide to views, and if they want more than default (and want to handle encryption), they would using a custom class.
