> I created a slider view in the Ambari-Admin UI. The view had one masked
> parameter {{ambari.server.password}}. I entered "admin" and saw in the POST
> that the decoded value was uploaded:
> {code}
> {
> "ViewInstanceInfo": {
> "instance_name": "s2",
> "label": "s2",
> "visible": true,
> "icon_path": "",
> "icon64_path": "",
> "properties": {
> "ambari.server.url": "http://tdk-1:8080/api/c1/clusters/tdk";,
> "ambari.server.username": "admin",
> "ambari.server.password": "admin",
> "view.kerberos.principal": "a",
> "view.kerberos.principal.keytab": "aa"
> },
> "description": "s2"
> }
> }
> {code}
> After saved, I editing and changed another param (say
> view.kerberos.principal). This broke the masked param. The reason is that the
> GET call to view parameters gives the encoded value.
> So POST takes decoded values and GET provides encoded values. So the next
> time UI PUTs, the encoded value is put resulting in original value corruption.
> The API should either always provided encoded or decoded values, but not both.
