---------------------------------------
Thanks [~vinodkv] for review/commit and [~aw] for comments.
bq. For trunk at least, it would probably be better to have a different var
that is handled via mapreduce's shellprofile.d bit.
This also sounds like a good way. Agree that we can discuss more later (on
another JIRA) for trunk.
bq. We will have to think more about the right-approach for trunk. Will open a
separate ticket for this.

> We already set lib jars on distributed-cache to CLASSPATH. However, in some
> corner cases (like: MR local mode, Hive Map side local join, etc.), we need

> runjar process.
