Zian Chen commented on YARN-8777:
---------------------------------
Thanks [~eyang] for the work. I'm ok with patch 003. One quick question, you
mentioned
{code:java}
It is entirely possible to use ProcessBuilder and launch container-executor to
run docker exec, and send unix command to be executed.
{code}
Is processbuilder mentioned to be an possible way for code reuse on passing
arbitrary commands? If yes, then this approach might run into similar issue
for enum approach, which can only handle a small set of command options not
arbitrary commands.

> Since Container Executor provides Container execution using the native
> container-executor binary, we also need to make changes to accept new
> “dockerExec” method to invoke the corresponding native function to execute
> docker exec command to the running container.
