Shane Kumpf commented on YARN-9562:
-----------------------------------
Thanks again, Eric! I'll give the latest patches a try.

These variables are used in create_local_dirs. I'm not super familiar with the
feature, but I was under the impression that they were not tied to any specific
runtime.
{quote}
You are correct. I guess I've overlooked this in the past.
{quote}What do you suggest as an alternative? Add both /tmp and /var/tmp as
tmpfs in the runC config?{quote}
My initial thought would be handling these mounts via the default-rw-mounts
setting in yarn-site vs hard coding it for every container. That said, I do see
the challenge that poses, since the mount is inside of the container work dir
in the current patch. For this initial cut, I'm fine with leaving it as is and
we can open an issue to revisit.
{quote}Agreed. Should I file JIRAs for the features or add comments into the
code or add documentation or what?{quote}
JIRAs under the runC umbrella maybe? or do we want to try to close that out
relatively quickly? I can help open the issues, I wasn't intending to put that
burden on you. :)
{quote} I don't want to attempt to install the packages for them. {quote}
Adding that check sounds like a reasonable solution to me without being
intrusive. No other issues to report on usability.

> This JIRA will be used to add the Java changes for the new
> RuncContainerRuntime. This will work off of YARN-9560 to use much of the
> existing DockerLinuxContainerRuntime code once it is moved up into an
> abstract class that can be extended.
