Shurong Mai updated YARN-9518:
------------------------------
Description:
When I had set configuration variables for cgroup with yarn, nodemanager could
be start without any matter. But when I ran a job, the job failed with these
exceptional nodemanager logs in the end.
In these logs, the important logs is " Can't open file /sys/fs/cgroup/cpu as
node manager - Is a directory "
After I analysed, I found the reason. In centos6, the cgroup "cpu" and
"cpuacct" subsystem are as follows:
{code:java}
/sys/fs/cgroup/cpu
/sys/fs/cgroup/cpuacct
{code}
But in centos7, as follows:
{code:java}
/sys/fs/cgroup/cpu -> cpu,cpuacct
/sys/fs/cgroup/cpuacct -> cpu,cpuacct
/sys/fs/cgroup/cpu,cpuacct{code}
"cpu" and "cpuacct" have merge as "cpu,cpuacct". "cpu" and "cpuacct" are
symbol links.
As I look at source code, nodemamager get the cgroup subsystem info by reading
/proc/mounts. So It get the cpu and cpuacct subsystem path are also
"/sys/fs/cgroup/cpu,cpuacct".
The resource description arguments of container-executor is such as follows:
{code:java}
cgroups=/sys/fs/cgroup/cpu,cpuacct/hadoop-yarn/container_1554210318404_0057_02_000001/tasks
{code}
There is a comma in the cgroup path, but the comma is separator of multi
resource. Therefore, the cgroup path is truncated as "/sys.fs/cgroup/cpu"
rather than correct cgroup path "
/sys/fs/cgroup/cpu,cpuacct/hadoop-yarn/container_1554210318404_0057_02_000001/tasks
"
