Re: Unable to find/start the Sandbox Tools

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.

@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!!

Michael_Rife · ‎04-05-2016

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.

Michael_Rife · ‎04-05-2016

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.

Michael_Rife · ‎04-05-2016

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.

Michael_Rife · ‎04-05-2016

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.

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.

Michael_Rife · ‎04-04-2016

Zeppelin Notebook worked for a couple queries in the Sandbox Tutorial Lab #6. It stopped working after a Step 6.3.1 (Hive Query). When I attempt to restart Zeppelin Notebook I get the following error in the /var/lib/ambari-agent/data/errors-495.txt file: urllib2.URLError: <urlopen error [Errno 111] Connection refused>

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.

Michael_Rife · ‎03-14-2016

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.

Michael_Rife · ‎03-14-2016

Thanks that granted access to Tez. I was able to

Michael_Rife · ‎03-14-2016

Did I miss that step in the tutorial? Are there steps for doing this on this web site? I am not a Unix admin, so steps for installing all these system pieces would help. Thanks.

Michael_Rife · ‎03-14-2016

Copied script from tutorial: a = LOAD 'geolocation' using org.apache.hive.hcatalog.pig.HCatLoader(); b = filter a by event != 'normal'; c = foreach b generate driverid, event, (int) '1' as occurance; d = group c by driverid; e = foreach d generate group as driverid, SUM(c.occurance) as t_occ; g = LOAD 'drivermileage' using org.apache.hive.hcatalog.pig.HCatLoader(); h = join e by driverid, g by driverid; final_data = foreach h generate $0 as driverid, $1 as events, $3 as totmiles, (float) $3/$1 as riskfactor; store final_data into 'riskfactor' using org.apache.hive.hcatalog.pig.HCatStorer(); I have -useHCatalog as "Arguments". Checked to run on TeZ. No data loaded into the riskfactor table.

Michael_Rife · ‎03-14-2016

When I click on the Ambari Views I cannot see the Storm, Tez View, or Zepplin.

Michael_Rife · ‎03-11-2016

OK. The key was I was expecting to see the HUE screen, but that does not exists. Yes I can get to Ambari, so I would assume all is up and running as expected. Hadoop in general can be an overwhelming ecosystem to start in. I will just run through all the tutorials and start reading books. Thanks to everyone who responded.

Michael_Rife · ‎03-10-2016

I redownloaded the VirtualBox and the OVA file is identical as my previous version. Where is the correct checksum for the VirtualBox VM OVA file published?

Michael_Rife · ‎03-10-2016

Sorry to be a pain, but all the Hortonworks Sandbox Youtube videos of previous versions show the ability access the Hadoop tools in this web page. I have tried Chrome, Firefox, and IE. All do the same.

Michael_Rife · ‎03-10-2016

@Scott Shaw I can get to the splash screen and all displays. I cannot get to the page that displays the Hadoop tools, the right side of the image below. HTTP://127.0.0.1/index.html only gives me the left frame. HTTP://127.0.0.1/index.html?popup=1 and popup=2 both now only display the left frame. There is no right frame. Was access to tools in a page like the right side of below removed from the Sandbox 2.4?

Michael_Rife · ‎03-10-2016

i have restarted the VM multiple times with no effect. I even reimported the OVA file into a new VM but the new VM has the same problem.

Michael_Rife · ‎03-09-2016

It spins for a while and then I get "This webpage is not available".

Michael_Rife · ‎03-09-2016

Installed Hortonworks with HDP 2.4 into Virtualbox with host OS of Windows 7. All installed fine. The VM starts up with no errors. When I go to http://127.0.0.1 I get the Sandbox splash screen, but no place to start the tutorials. I saw on the Hortonworks videos a "Start Tutorials" button that takes you to a web page where the frame on the left is the tutorial and the frame on the right is the Sandbox tools. If I go to http://127.0.0.1/frames.html I get the page with the tutorial on the left, but the right side is blank where the Sandbox tools are supposed to be.
