Wangda Tan commented on YARN-2901:
----------------------------------
Patched and tried, UI looks great! One suggestion is: do we need fold single
line message when line is too long to be:
{{Unable to load native-hadoop library for your platform... using builtin-java
cla}}
{{Unable to load native-hadoop library for your platform... using builtin-java
classes where applicable}}
Actually the 2nd line can be entirely show in one line.
I think this is caused by hard coded column width, can we make it dynamic under
different environment?
Maybe we need always not fold one line message?
Will include implementation review in next review.

> It would be really useful to have statistics on the number of errors and
> warnings in the RM and NM web UI. I'm thinking about -
> 1. The number of errors and warnings in the past 5 min/1 hour/12 hours/day
> 2. The top 'n'(20?) most common exceptions in the past 5 min/1 hour/12
> hours/day
> By errors and warnings I'm referring to the log level.
> I suspect we can probably achieve this by writing a custom appender?(I'm open
> to suggestions on alternate mechanisms for implementing this).
