dataFrame.cache() returning all rows

[benjami...@gmail.com]

Hi,

just getting started with spark-notebook, but it seems to me that when I do a cache() or persist() of a data frame, spark-notebook is retrieving all results and trying to show them in a tabular view in the cell output as if it were a collect(), which is not quite appropriate for my usage (presentation). 

Is this something that can be disabled?

Thanks,

benjamin
