Yarn containers creating child process

Hi,

What are the features available to limit the Yarn containers from creating
the child process?

Thanks

Hi Sandesh!

A *yarn* task is just like any other process on the operating system.
Depending on which ContainerExecutor you use, you should launch the yarn
task with appropriate limits in place. Although I have never tried it, on
Linux you could use setrlimit or
https://www.kernel.org/doc/Documentation/cgroup-v1/pids.txt . What yarn
application are you planning on using? Or creating your own?

HTH
Ravi.
