Did you try setting your interpreter to “Isolated” mode? Is it currently in “shared” mode?
If you haven’t played with this setting before then: 1. Open the interpreters page 2. Find your interpreter and click the edit button in the top right corner 3. Beneath the word “option” at the top left there should be a drop down that says “shared”, “scoped”, or “isolated”. 4. Set that drop down to isolated and then scroll down and click save. By doing that, we get a separate YARN application for each notebook running on the same interpreter. http://www.placeiq.com/ http://www.placeiq.com/ http://www.placeiq.com/ Paul Brenner https://twitter.com/placeiq https://twitter.com/placeiq https://twitter.com/placeiq https://www.facebook.com/PlaceIQ https://www.facebook.com/PlaceIQ https://www.linkedin.com/company/placeiq https://www.linkedin.com/company/placeiq DATA SCIENTIST (217) 390-3033 http://www.placeiq.com/2015/05/26/placeiq-named-winner-of-prestigious-2015-oracle-data-cloud-activate-award/ http://placeiq.com/2015/12/18/accuracy-vs-precision-in-location-data-mma-webinar/ http://placeiq.com/2015/12/18/accuracy-vs-precision-in-location-data-mma-webinar/ http://placeiq.com/2015/12/18/accuracy-vs-precision-in-location-data-mma-webinar/ http://placeiq.com/2015/12/18/accuracy-vs-precision-in-location-data-mma-webinar/ http://placeiq.com/2016/03/08/measuring-addressable-tv-campaigns-is-now-possible/ http://placeiq.com/2016/04/13/placeiq-joins-the-network-advertising-initiative-nai-as-100th-member/ http://placeiq.com/2016/04/13/placeiq-joins-the-network-advertising-initiative-nai-as-100th-member/ http://placeiq.com/2016/04/13/placeiq-joins-the-network-advertising-initiative-nai-as-100th-member/ http://placeiq.com/2016/04/13/placeiq-joins-the-network-advertising-initiative-nai-as-100th-member/ http://placeiq.com/2016/04/13/placeiq-joins-the-network-advertising-initiative-nai-as-100th-member/ http://pages.placeiq.com/Location-Data-Accuracy-Whitepaper-Download.html?utm_source=Signature&utm_medium=Email&utm_campaign=AccuracyWP http://placeiq.com/2016/08/03/placeiq-bolsters-location-intelligence-platform-with-mastercard-insights/ http://placeiq.com/2016/10/26/the-making-of-a-location-data-industry-milestone/ http://placeiq.com/2016/12/07/placeiq-introduces-landmark-a-groundbreaking-offering-that-delivers-access-to-the-highest-quality-location-data-for-insights-that-fuel-limitless-business-decisions/ On Wed, Jan 25, 2017 at 9:12 PM Alec Lee < mailto:Alec Lee <alec.in...@gmail.com> > wrote: a, pre, code, a:link, body { word-wrap: break-word !important; } Hello, Paul Thank you so much for prompt reply. Our understanding is each interpreter takes one application on YARN, if multiple notebooks share same interpreter will run through same YARN application. As you mentioned this “… which will kill any other YARN application associated with that interpreter.” , we seem never see more than one YARN application in YARN UI, the case we had, I use one interpreter but wrote many notebooks, but no matter how many notebooks spark jobs, I only see one YARN application. So I am curious how to make single interpreter being associated with more than YARN applications.

That way each notebook gets it’s own application on yarn. This mostly works well. The one downside is that if you stop a notebook (e.g. by calling sys.exit in a cell of a spark notebook) it does stop the YARN application most of the time but you can’t restart that notebook until you have restarted the interpreter… which will kill any other YARN application associated with that interpreter. So our full setup is that we give each user an interpreter (which is good because we can set each user’s interpreter to have their username in spark.yarn.queue) and set each user’s interpreter to isolated. Honestly I still don’t understand what scoped does… maybe that would work as well? http://www.placeiq.com/ http://www.placeiq.com/ http://www.placeiq.com/ Paul Brenner https://twitter.com/placeiq https://twitter.com/placeiq https://twitter.com/placeiq https://www.facebook.com/PlaceIQ https://www.facebook.com/PlaceIQ https://www.linkedin.com/company/placeiq https://www.linkedin.com/company/placeiq DATA SCIENTIST (217) 390-3033 http://www.placeiq.com/2015/05/26/placeiq-named-winner-of-prestigious-2015-oracle-data-cloud-activate-award/ http://placeiq.com/2015/12/18/accuracy-vs-precision-in-location-data-mma-webinar/ http://placeiq.com/2015/12/18/accuracy-vs-precision-in-location-data-mma-webinar/ http://placeiq.com/2015/12/18/accuracy-vs-precision-in-location-data-mma-webinar/ http://placeiq.com/2015/12/18/accuracy-vs-precision-in-location-data-mma-webinar/ http://placeiq.com/2016/03/08/measuring-addressable-tv-campaigns-is-now-possible/ http://placeiq.com/2016/04/13/placeiq-joins-the-network-advertising-initiative-nai-as-100th-member/ http://placeiq.com/2016/04/13/placeiq-joins-the-network-advertising-initiative-nai-as-100th-member/ http://placeiq.com/2016/04/13/placeiq-joins-the-network-advertising-initiative-nai-as-100th-member/ http://placeiq.com/2016/04/13/placeiq-joins-the-network-advertising-initiative-nai-as-100th-member/ http://placeiq.com/2016/04/13/placeiq-joins-the-network-advertising-initiative-nai-as-100th-member/ http://pages.placeiq.com/Location-Data-Accuracy-Whitepaper-Download.html?utm_source=Signature&utm_medium=Email&utm_campaign=AccuracyWP http://placeiq.com/2016/08/03/placeiq-bolsters-location-intelligence-platform-with-mastercard-insights/ http://placeiq.com/2016/10/26/the-making-of-a-location-data-industry-milestone/ http://placeiq.com/2016/12/07/placeiq-introduces-landmark-a-groundbreaking-offering-that-delivers-access-to-the-highest-quality-location-data-for-insights-that-fuel-limitless-business-decisions/ On Wed, Jan 25, 2017 at 8:20 PM Alec Lee < mailto:Alec%20Lee%20<alec.in...@gmail.com> > wrote: Hi, all Currently we are exploring feature of zeppelin, now the situation we are using YARN to manage spark jobs. In terms of the experiments, we conclude that one interpreter is corresponding to An application in YARN cluster, that means all the notebooks from zeppelin with same interpreter go through single Application in YARN. Also we found if out code shuts down the application in YARN, then any notebooks fail to run after this point - error like this “can’t call a stop spark context …..” . The only solution for this is to restart the interpreter. How to get around this without restart the interpreter? Thanks AL
