Sreenath Somarajapuram commented on TEZ-2843:
---------------------------------------------

1. Wouldn't it be better to stop polling on failure?
2. Trailing space at the end of "Failed To get in progress status. Manually 
refresh to update status",
3. Is this change required
{code}
-      amInfoUpdateService = App.Helpers.Pollster.create({
+      amInfoUpdateService = App.Helpers.Pollster.createWithMixins({
         onPoll: function() {
           that.updateAMDagInfo();
           that.updateAMVerticesInfo();
-        }
+        },
{code}
