Andras Piros commented on OOZIE-2687:
-------------------------------------

We have to make sure {{<global><launcher>...</launcher></global>}} applies to appropriate action types only.

> It was possible to manipulate the MapperLauncher's environment through properties like:
> # mapreduce.map.memory.mb	
> # mapreduce.map.cpu.vcores
> # mapred.child.env
> # mapred.child.java.opts	
> # mapred.job.queue.name  - ability to set launcher queue
> E.g. We were using mapred.child.env to pass SPARK_HOME to the LauncherMapper and make PySpark work. 
> Fixing OOZIE-2596 added a hack. We should decide how we support or break compatibility and how we allow the manipulation of the Launcher environment.
