Hue is not included with the current version of the sandbox. All activities are done either through Ambari or from the OS prompt. If you want to use Hue, you would have to "side load" it onto your sandbox. I am sure there are instructions as to how to do that out on the Internet. I did not do that. We want to stay "stock" Hortonworks. ... View more

@Chuck D'Antonio, I had the same problem. I had an empty notebook (empty note.json file). I moved the directory to /tmp and the Zeppelin Notebook server started. I assume that I can now drop the directory I moved to /tmp. Thanks!! ... View more

I compared the start up logs from when Zeppelin last successfully started and the last time I attempted to start it and it did not start. The left side is the successful startup log. The right is the unsuccessful startup log. ... View more

Thanks for the suggestion. I stopped the processes you have stopped, but Zeppelin Notebook would not start with same error. I restarted the VM. Zeppelin shows green upon the OS startup, but it is not running when I look at the Amari dashbord. ... View more

Did not make any VM changes. A single table query worked. Then I tried the query joining two tables in the tutorial. No results were returned. After quite a while I refreshed the browser (F5) and at that point Zeppelin notebook stopped and I have not been able to get it started. ... View more

I let it sit but nothing happened. I tried to restart the services. Same error. I shut down the VirtualBox machine and restart the Sandbox. Zeppelin-Notebook did not start. It fails at 100% and is remains red. I still get the following error: urllib2.URLError: <urlopen error [Errno 111] Connection refused> When I start the Sandbox it says that Zeppelin started with a green OK, but when I go into Ambari it does not start Zeppelin Notebook. Also, it now appears that Spark is not starting as well. ... View more

I am new to Hadoop/Horton works. How do I know what are considered unnecessary services? It was running before I did the Hive join query in the tutorial. Now it does not work. No new services starts or changed. ... View more

Mine was Created on: 29_02_2016_18_58_23 for virtualbox. The newer version has it corrected. I do not see a way to grant access to the Storm or Zeplin views in Ambari. ... View more

Bingo. I copied "–useHCatalog" instead of "-useHCatalog". The first character was the "long dash" character instead of the "short dash" character. The font in tutorial document should be changed to use the short dash. Or the user should just copy the correct text where it is actually double quoted. 😉 Thanks. ... View more
