@Ahmad Hassan , can you please follow this tutorial and check that you have gone through all steps. Further, can you please try 127.0.0.1:8080 in different browsers?

@Ahmad Hassan , the latest sandbox has a lot of useful components running in it, so it needs at least 8 GB of RAM itself. So your laptop should have more than 8GB of RAM, perhaps 12 or 16.

@Dmitry Otblesk , There is 1 datanode already installed in the Sandbox. Can you please try to start the datanode component from Ambari? Let us know about the error if you receive any.

@Fru N. you are trying to load /tmp/demo/piglab04/data/drivers.tsv but your file has a csv extension. Change from tsv to csv. It should work.

it says that the input path does not exist, can you also show the output of this command: hdfs dfs -ls /tmp/demo/piglab04/data/

@Fru N., you do not have to change anything in hdfs-site.xml. Can you please send entire job log.

mrizvi · ‎12-08-2016

@Fru N. can you check whether the file is present at the specified location, and if yes, what are the permissions for that file?

Hi guys, I am trying to display ggplots from Zeppelin Livy SparkR interpreter. I get something like ggplot-nullmessage.png. I also tried using ggsave to save the plots to the disk and it is working fine, ggplot(delay_r, aes(x=STATUS,y=Percentage,fill=STATUS)) + geom_bar(stat="identity") + geom_text(aes(label=STATUS), size = 7) + ylim(0,100) ggsave(file="/tmp/plot.png") Can someone please guide me to display this plot in Zeppelin only?

that makes perfect sense, thanks a lot.
