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
