Hi, Is there a date/plan to integrate this PR to main branch of Zeppelin ?
I have found this to be very useful in sharing data/model's prediction result between SparkR and R and then use visualization packages of R to visualize the prediction results. Also demonstrated the same to many others who also liked and found it useful. Especially given that in Jupyter the data cannot be shared between R and Spark without serializing/persisting the data, this feature is pretty much differentiatior for Zeppelin. So wondering is there a plan/date for this PR to be available in the main branch ? Regards, Sourav On Thu, Dec 24, 2015 at 11:01 AM, Amos B.
