https://github.com/apache/zeppelin/pull/2502
@felixcheung I have added a couple of paragraphs of documentation including
an example showing interaction between the Scala and SQL interpreters to
_spark.md_ (at the end of the text under the title [Object
Exchange](https://zeppelin.apache.org/docs/0.7.2/interpreter/spark.html#object-exchange)
and just above the title [Form
Creation](https://zeppelin.apache.org/docs/0.7.2/interpreter/spark.html#form-creation).
