Now that Spark has been integrated into Bigtop:
    https://issues.apache.org/jira/browse/BIGTOP-715
it may make sense to tackle some of those issues from a
distribution perspective. Bigtop has a luxury of defining an
entire distribution (you always know what versions of Hadoop
and its ecosystem projects your're dealing with). It also
provides helper functionality for a lot of common things (like
finding JAVA_HOME, plugging into the underlying
OS capabilities, etc.).

I guess all I'm saying is that you guys should consider Bigtop
as an integration platform for making Spark easier to use.

Feel free to fork off this thread to dev@bigtop (CCed) if you
think this is an idea worth exploring.

Thanks,
Roman.
