Bikas Saha commented on YARN-3911:
----------------------------------
I am sorry for the super delayed response. For some reason I was not a watcher
on this. By tail I did not mean linux tail command but just the concept of
sending the last set of entries (say last 4K of data) from the stderr and/or
syslog if the container launch fails.
> Add tail of stderr to diagnostics if container fails to launch or it
> container logs are empty

> The stderr may have useful info in those cases.
