Subject Re: Yarn ResourceManager web UI does not show job

No, you cant show them in RM UI then.

However if you can start another daemon, you can consider using YARN
Application History/Timeline Server or MR Job History Server(only for MR
jobs)  to see information about completed jobs.
You can look up Hadoop documentation to learn more about them and how to
configure them.

Just to clarify though, the apps themselves are not lost, as in, the output
is not lost. Its just the information about them which is no longer present
on RM restart.
