> 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.
