Eric Payne commented on YARN-4422:
----------------------------------
bq. Thanks! Will this fix address MAPREDUCE-5502 or MAPREDUCE-4428? It doesn't
seem so, but would like to confirm.
[~mingma], thanks for your interest. No, this JIRA does not fix the issue
documented in MAPREDUCE-5502 or MAPREDUCE-4428. This JIRA only affects the
Generic application history server's GUI and not the RM Application GUI. Also,
as documented in those JIRAs, the problem is not a missing link in the GUI, but
that the log history is missing altogether.
> Generic AHS sometimes doesn't show started, node, or logs on App page

> 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}}.
