Daniel Templeton commented on YARN-5388:
----------------------------------------

Post MAPREDUCE-6719, the DCE is broken, and it isn't deprecated before this 
patch.  I don't think it's reasonable to say that slapping a deprecation label 
on something absolves us from fixing it when it's broken.  The label says that 
it will go away in the future, not that it's broken and cannot be used.

> MAPREDUCE-6719 requires changes to DockerContainerExecutor

> Because the {{DockerContainerExecuter}} overrides the {{writeLaunchEnv()}} 
> method, it must also have the wildcard processing logic from 
> YARN-4958/YARN-5373 added to it.  Without it, the use of -libjars will fail 
> unless wildcarding is disabled.
