Billie Rinaldi commented on YARN-8963:
--------------------------------------
+1 for patch 3. I verified that the feature.terminal.enabled flag controls
whether or not a shell can be opened for a container. In the UI, the feature
disabled message is displayed, but at the command line the connection appears
to be closed without the message being displayed. I suspect this is due to
inconsistent flushing after writing to stderr, which I have opened YARN-9129 to
address. Thanks for the patch, [~eyang]!

> For some production job, application admin might choose to disable debugging
> to production jobs to prevent developer or system admin from accessing the
> containers. It would be nice to add an environment variable flag to disable
> interactive shell during application submission.
