getting pid for yarn container

[Jae-Hyuck Kwak <jh...@kisti.re.kr>]

Hi,
I'd like to monitor actual resource usage (cpu utilization, memory 
usage, io usage, etc)
of the yarn containers by external tools.

Is there any way to get process id(pid) of yarn container?

BR,
Jae-Hyuck

Hi,

I don't know whether there is a more efficient way, but this works:
 1. get the host name or IP of the node the container is running
 2. login to this node
 3. grep the process table for the container ID (it's passed as argument to Java)
    $ ps aux | grep container_...
    yarn  16076  .../bin/java ...
-Dyarn.app.container.log.dir=.../yarn/log/application_1512553291624_0087/container_1512553291624_0087_01_000796
 4. the pid is 16076

Best,
Sebastian
