Using R intrepreter in zeppelin

Hi, I am using zeppelin 0.7.1 with mesos. I installed R on the master node where zeppelin is installed( as mentioned in the documentation here ). But when I run R code, its getting failed (error: sparkr is not responding) when th

So far no one else has responded so perhaps I am the only one who has experienced this. If I can figure out steps to reproduce then I’ll definitely open a ticket. http://www.placeiq.com/ http://www.placeiq.com/ http://www.placeiq.com/ Paul Brenner https://twitter.com/placeiq https://twitter.co

Will there be steps to reproduce the problem? And please feel free to open a JIRA issue. Thanks, moon On Tue, May 2, 2017 at 8:48 AM Paul Brenner wrote: > Has anyone else encountered this? Sometimes when I use z.show to show a > data frame I can select the text that is shown (for easy copy and

Re: Customizing sparkconfig before starting spark app

Hi, For now, there's no special way to configure spark app name from notebook while Zeppelin initialize SparkContext before execute any code in the notebook. Registering custom kryo serializer is no different from spark-shell, i think. Submitting job as a logged in user is depends on how your co

Re: Can't download moderately large data or number of rows to csv

We came across this issue as well, Zeppelin csv export is using the data URI scheme which is base64 encoding all the rows into a single string, Chrome seems to crash with over a few thousand rows, but Firefox has been able to handle over 100k for me. However, the Zeppelin notebook itself becomes sl

Re: Can't download moderately large data or number of rows to csv

Good idea to introduce in Zeppelin a way to download full datasets without actually visualizing them. Not sure if this helps, we taught our users to use %sh hadoop fs -getmerge /hadoop/path/dir/ /some/nfs/mount/ for large files (they sometimes have to download datasets with millions of records). T

Can't download moderately large data or number of rows to csv

There are limits to how much data the download to csv button will download (1.5MB? 3500 rows?) which limit zeppelin’s usefulness for our BI teams. This limit comes up far before we run into issues with showing too many rows of data in zeppelin. Unfortunately (fortunately?) Hue is the other tool

Selecting z.show() text in chrome sometimes doesn't work

Has anyone else encountered this? Sometimes when I use z.show to show a data frame I can select the text that is shown (for easy copy and pasting into a .filter() for example). However, other times I just can’t select the text. I have no idea what causes the problem to come or go away. Can anyon
