I think it will fail for Hadoop < 2.4.
The hadoop server code that recognizes `<CPS>` was committed at Mar 17
2014, to resolve YARN-1824. The code is in
org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.
([see this github
link](https://github.com/apache/hadoop-common/blob/9f02e3a4a70d4affd5342e8fa61666bd8bf59bbb/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/containermanager/launcher/ContainerLaunch.java))
So, maybe the best solution that does not require Hadoop 2.4.0 is to build
the environment variables on the cluster side. (I don't know how to do that -
is it even possible?)
