> 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}}.
