Li Lu updated YARN-2242:
------------------------

    Description: 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.   (was:
