must be absolute and no environment variable substitution will be performed. The paths are compared LOCAL_INVARIANT case insensitive string comparison,
the file path validated must start with one of the paths listed in local-dirs configuration. Use comma as path separator:<<<,>>>
<<<yarn.nodemanager.windows-secure-container-executor.job-name>>> should contain an Windows NT job name that all containers should be added to.
This configuration is optional. If not set, the container is not added to a global NodeManager job. Normally this should be set to the job that the NM is assigned to,
so that killing the NM kills also all containers. Hadoopwinutilsvc will not attempt to create this job, the job must exists when the container is launched.
If the value is set and the job does not exists, container launch will fail with error 2 <<<The system cannot find the file specified>>>.
Note that this global NM job is not related to the container job, which always gets created for each container and is named after the container ID.
This setting controls a global job that spans all containers and the parent NM, and as such it requires nested jobs.
Nested jobs are available only post Windows 8 and Windows Server 2012.
