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…

Using Zeppelin 0.7.3, Spark 2.1.0-mapr-1703 / Scala 2.11.8
I had previously run the demo and successfully set up MongoDB and
JDBC interpreter for Impala under V0.7.2. Since I have upgraded to
0.7.3, everything broke. I am down to to complete re-install
(several, in fact) and get a response like below for most everything
I try. (Focusing just on %spark for now) apparently have something
very basic wrong, but I'll be damned if I can find it. The same
example works fine in spark-shell.
Any suggestions for a new guy very much appreciated.
I found[ZEPPELIN-2475] and

which seem to be the same, or similar, but I did not understand what
to change where
