custom JAVA_HOME

Should Apex add JAVA_HOME to DAGContext and allow application to specify 
which JDK to use if there are multiple JDK installations on Hadoop 
cluster? Yarn already supports custom JAVA_HOME (please see 
https://issues.apache.org/jira/browse/YARN-2481).

    Are there any in the list that one can see as conflicting with our own
    environment variables? For e.g. LOGNAME?

+1 for the idea.
Are there any in the list that one can see as conflicting with our own
environment variables? For e.g. LOGNAME?

How about allowing specification of all environment variables supported by
YARN that are non-final described below
