I feel Ember way to do that would be to convert title into a computed property.
In-fact code in tez-ui/src/main/webapp/app/routes/abstract.js is designed for
that.
For example. Title in tez-ui/src/main/webapp/app/routes/vertex/tasks.js could
be changed as follows.
{code}
title: Ember.computed(function () {
var vertex = this.modelFor("vertex"),
vertexName = vertex.get("name"),
entityID = vertex.get("entityID");
return `Vertex Tasks: ${vertexName} (${entityID})`;
}).volatile(),
{code}
Please note the extra ".volatile()" function call. Its added so that the
compute function is called always.
As we don't have a direct path to the values its necessary (As we are getting
the vertex object via modelFor). Else the volatile call could have been avoided.

> In Tez UI 0.7, DAG (vertex, app, task, attempt) context was shown in the
> document title. This was lost in the 0.9 UI migration. This jira attempts to
> bring that feature back. This feature is essential when supporting large
> clusters where a dev or support person may have dozens of dags open at the
> same time. Having context in the document title (the tab title), will allow
> us to quickly navigate.
