Li Lu updated YARN-2242:

    Attachment: YARN-2242-070814.patch

New patch to add the swallowed diagnostics information back, also reformatted 
the exception output for easy understanding. Now the exception output contains 
all original exception information, also a pointer to the logs. Addressed 
[~ste...@apache.org]'s null URL issue by adding one more branch.

> Now on each time AM Container crashes during launch, both the console and the 
> webpage UI only report a ShellExitCodeExecption. This is not only unhelpful, 
> but sometimes confusing. With the help of log aggregator, container logs are 
> actually aggregated, and can be very helpful for debugging. One possible way 
> to improve the whole process is to send a "pointer" to the aggregated logs to 
> the programmer when reporting exception information.
