Sreenath Somarajapuram commented on TEZ-2043:
---------------------------------------------

A trailing space in app.js, vertex_controller.js and dag_vertices.js

Few suggestion:

1. The following can be added into the fractionToPercentage function itself to 
reduce duplication.
+    var pct;
+    if (Ember.typeOf(this.get('progress')) === 'number') {
+      pct = App.Helpers.number.fractionToPercentage(this.get('progress')) + ' 
%';
+    }
+    return pct;

2. Same with the following snippet, it can be defined in one place (may be 
dag_controller.js) and reused from other places.
+          if (dag.get('status') === 'RUNNING') {
+            amInfoFetcher = store.find('dagProgress', dag.get('id'), {
+              appId: dag.get('applicationId'),
+              dagIdx: dag.get('idx')
+            })
+            .then(function(dagProgressInfo) {
+              dag.set('progress', dagProgressInfo.get('progress'));
+            })
+            .catch(function(error) {
+              Em.Logger.error('Failed to fetch dagProgress' + error);
+            });
+            loaders.push(amInfoFetcher);
+          }

> tez-ui add progress info from am webservice to dag and vertex views
