> Sometimes the AM container for an app isn't able to start the JVM. This can 
> happen if bogus JVM options are given to the AM container ( 
> {{-Dyarn.app.mapreduce.am.command-opts=-InvalidJvmOption}}) or when 
> misconfiguring the AM container's environment variables 
> ({{-Dyarn.app.mapreduce.am.env="JAVA_HOME=/foo/bar/baz}})
> When the AM container for an app isn't able to start the JVM, the Application 
> page for that application shows {{N/A}} for the {{Started}}, {{Node}}, and 
> {{Logs}} columns. It _does_ have links for each app attempt, and if you click 
> on one of them, you go to the Application Attempt page, where you can see all 
> containers with links to their logs and nodes, including the AM container. 
> But none of that shows up for the app attempts on the Application page.
> Also, on the Application Attempt page, in the {{Application Attempt 
> Overview}} section, the {{AM Container}} value is {{null}} and the {{Node}} 
> value is {{N/A}}.
