Vinod Kumar Vavilapalli reopened YARN-2242:
-------------------------------------------
This is not the right solution - you are swallowing diagnostics from the
container. Imagine AM container failing due to localization failure, we want to
show the right diagnostics there. The solution for this ticket is to change the
message on the NM side, not the RM side.

> 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.
