--------------------------------------
Hi [~Naganarasimha]
Good point. I just looked at the code a bit, however, I did not find a default
{{YarnConfiguration. NM_LINUX_CONTAINER_CGROUPS_MOUNT_PATH}}. Looks like it is
reasonable to set a default value such as
{code}
NM_LINUX_CONTAINER_CGROUPS_MOUNT_PATH_DEFAULT=/sys/fs/cgroup
{code}
hmm ... but there seems more work. If we set a default value to
{{/sys/fs/cgroups}} and use that as default. If user sets
{{yarn.nodemanager.linux-container-executor.cgroups.mount}} without explicitly
setting {{yarn.nodemanager.linux-container-executor.cgroups.mount-path}}, it
will mount cgroups to {{/sys/fs/cgroups}} no matter what under neath linux
distribution is, would that cause problems? Looks like we need a check here.
What do you think?
