    to the cgroup filesystem (usually /sys/fs/cgroup/) and\n# introspect the statistics
    for the cgroup for the given\n# hierarchy. Alas, Docker breaks this by mounting
    the container\n# statistics at the root while leaving the cgroup paths as the
    actual\n# paths. Therefore, Elasticsearch provides a mechanism to override\n#
    reading the cgroup path from /proc/self/cgroup and instead uses the\n# cgroup
    path defined the JVM system property\n# es.cgroups.hierarchy.override. Therefore,
    we set this value here so\n# that cgroup statistics are available for the container
