> It would be great if we log vital information such as classpath, etc. upon a
> mapreduce child JVM start. This would help a great deal in terms of
> troubleshooting classpath issues, etc. Today it is pretty difficult to debug
> this unless you preserve the container script.
> Maybe it can log things like classpath, os name/version, java version, etc.
> at the beginning of the child JVM start.
