> 1. Code to display error log and error bar is duplicated everywhere. Create a helper function that accepts an error object and does the same. Also replace all the duplicate code with this function.
> 2. When ATS is down, I see the following message: 
> "error code: Unknown, message: Error while loading tez-app.index.
> Could not retrieve expected data from Timeline Server @ http://localhost:8188/ws/v1/timeline/TEZ_APPLICATION/tez_application_1447798385040_0001"
> It seems wrong to print unknown error code.
> 3. "Info! Could not fetch application info from RM (yarn system metrics publishing might be disabled), some details might be missing" 
> This message should be changed to "Info! Could not fetch application info from YARN RM/Timeline (yarn system metrics publishing might be disabled), some details might be missing"
