-----------------------------------------------------------

A recent fix in YARN now pushes the contents of the launch container script to the application logs. Given that change, do we still need this fix? 

Or to put it differently, should we be considering enhancing yarn to log some of these things as part of the launch container script itself instead of having all apps build the same functionality?

> MapReduce displays JVM system properties via config {{mapreduce.jvm.system-properties-to-log}} in both AM and task log . This is useful to debug env setting such as java version, etc. It is useful to have such logging in Tez.
