This is how the documentation of {{linux-container-executor.cgroups.mount-path}} would look like: > {noformat} > Requested cgroup mount path. Yarn has built in functionality to discover > the system cgroup mount paths, so use this setting only, if the discovery does not work. > This path must exist before the NodeManager is launched. > The location can vary depending on the Linux distribution in use. > Common locations include /sys/fs/cgroup and /cgroup. > If cgroups are not mounted, set yarn.nodemanager.linux-container-executor.cgroups.mount > to true. In this case it specifies, where the LCE should attempt to mount cgroups if not found. > If cgroups is accessible through lxcfs or some other file system, > then set this path and yarn.nodemanager.linux-container-executor.cgroups.mount to false. > Yarn tries to use this path first, before any cgroup mount point discovery. > If it cannot find this directory, it falls back to searching for cgroup mount points in the system. > Only used when the LCE resources handler is set to the CgroupsLCEResourcesHandler > {noformat} -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
