> Project: Oozie
> Issue Type: Sub-task
> Reporter: Peter Cseh

>
> 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.
