discover version of spark running?

[John Langley <di...@gmail.com>]

I'm hacking with zepplin and ran into the issue related to
bank.registerTempTable("bank") problem that Taotao.Li mentioned.

In order to understand what was going on, I thought I'd just print the
version of Spark running. But somehow I couldn't find the docs for printing
that. (I thought I'd just interactively print it via zeppelin)

Anyone have a quick pointer of how to do that?

Thanks in advance,
