Re: Trying to 0.7.3 running with Spark

[Terry Healy]

Hi Michael-

I'm not sure what the values are supposed to be in order to compare. The 
interpreter is running; a save and restart still gives the same result.

What do you see when you check out the spark interpreter?  Something 
with %spark, or %spark.sql   (Sorry, going from memory. ) I think it 
may also have to do with not having the spark interpreter running, so 
if you manually restart the interpreter then re-run the notebook… it 
should work…
