%spark
val a = 1
%dep
z.reset()
z.addRepo("Spark Packages Repo").url("http://dl.bintray.com/spark-packages/maven")
z.load("com.databricks:spark-csv_2.10:1.2.0")
a: Int = 1
<console>:28: error: not found: value %
%dep

Answer 1

Each cell can hold one type of interpreter. Thus is order to use %dep and %spark you should separate them into two cells starting with %dep after restarting the spark interpreter so it can be taken into consideration. e.g :
In the first cell :
%dep
z.reset()
z.addRepo("Spark Packages Repo").url("http://dl.bintray.com/spark-packages/maven")
z.load("com.databricks:spark-csv_2.10:1.2.0")
Now that your dependencies are loaded, you can access spark interpreter in a different cell:
%spark
val a = 1
PS: By default, a cell runs with the spark interpreter so you don't need to explicitly use %spark.
