Subject [jira] [Commented] (YARN-2901) Add errors and warning stats to RM, NM web UI
Date Sat, 21 Mar 2015 00:09:38 GMT

    [ https://issues.apache.org/jira/browse/YARN-2901?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14372351#comment-14372351
] 

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).
