Hi, I am unable to see any plots or graphs when I run a chunk of code in RNoteBook. But I am able to see them in the plots pane, when I run it from the console. What could be the reason for this behavior?

Got it working finally, thanks to @Robert Hryniewicz. Go to interpreter settings page and add the new property under livy settings - livy.spark.jars.packages and the value com.databricks:spark-csv_2.10:1.4.0. Restart the interpreter and retry the query.

try ssh -p2222 root@xx.xx.xx.xx' the allocated IP then it will ask where you want to add say yes change unix password then run command 'ambari-admin-password-reset' it will allow you to change the password for ambari admin

Thanks so much. I was struggling to find it until now.

Never mind, just got this thread https://github.com/SKKU-SKT/ggplot2.SparkR/issues/8. Right now, there is no package yet. Will have to wait then. I switched back to 1.6.2 and above command is working.

Never mind, got this working. The problem was the double quote so I changed the replace string to ${twitter.msg:replaceAll('[$&+,:;=?@#|\'<>.^*()%!-]',''):replace('"',''):replace('\n','')} and it worked.

You could also drop null values from your initial columns with: train_df <- dropna(train_df,cols = 'ARR_DELAY')

@WeiHsiang Tseng, Firstly, try with 8090, not 9080. When you say close, what you are referring to? Have you logout from the shell or power off the image from VirtualBox. In the latter case, if your Sandbox is not up and running, you will not be able to access 8090 port
