Description

Currently the hadoop-yarn-project/hadoop-yarn/conf/container-executor.cfg example config file does not contain a gpu section. According to the apache Hadoop wiki page this is the way how you enable using gpus:

[gpu]
  module.enabled=true

I didn't see any other related configs just like in the case of fpga or pluggable device, but I think we can add that short part to show that the gpu feature works.
