View resource consumption for the yarn container

The running program on yarn is executed by container, so when we want to know how each node corresponds to the container, we need to start with it.

At first I thought yarn system command will have corresponding prompts, so yarn--help, there is no information I want. So on the other hand: Linux systems.

1. First look at which thread is more like the thread we're looking for, lock the thread ID

2. cd/proc/

3. LS--it's all about running threads.

4. CD thread ID number (in the form of a folder)

5. Ls-ail

As you can see from the above information, this is the container we're looking for.
