https://jira.apache.org/jira/browse/ZEPPELIN-3471 <https://jira.apache.org/jira/browse/ZEPPELIN-3471> This is a clustered design specifically designed to run multiple zeppelin instances simultaneously.
If you implement this feature yourself, First, multiple zeppelin instances must be able to know each other. Then let multiple zeppelins communicate with each other, When permissions and notes change, Keep all zeppelin instances in sync by broadcasting messages. Here is the design documentation: https://docs.google.com/document/d/1a8QLSyR3M5AhlG1GIYuDTj6bwazeuVDKCRRBm-Qa3Bw/edit#heading=h.s41ckl271z8s <https://docs.google.com/document/d/1a8QLSyR3M5AhlG1GIYuDTj6bwazeuVDKCRRBm-Qa3Bw/edit#heading=h.s41ckl271z8s> Currently zeppelin's clustering has been submitted to the community for code merging. Because this function is implemented, it is more complicated and requires careful review. So it is recommended to wait for the community to complete the merging of the code. :-) > 在 2019年3月25日，上午11:36，Horoschun, Matthew <matthew.horosc...@capgemini.com> 写道： > > Hi Bailin > > My understanding is that even if you store notebooks in S3 (as we do), these > are only loaded on Zeppelin start up so having multiple Zeppelin instances > isn’t viable at the moment. > > I believe there are open tasks to make HA deployment of Zeppelin possible. > E.g. https://jira.apache.org/jira/browse/ZEPPELIN-3778 > <https://jira.apache.org/jira/browse/ZEPPELIN-3778> for notebook > synchronisation. > > If you know a way to work around this with 0.8, I’d be keen to hear! > > Matthew > > > From: "bailin....@refinitiv.com" <bailin....@refinitiv.com> > Reply-To: "users@zeppelin.apache.org" <users@zeppelin.apache.org> > Date: Monday, 25 March 2019 at 1:21 pm > To: "users@zeppelin.apache.org" <users@zeppelin.apache.org> > Subject: Re: Dynamic updation of notes across multiple Zeppelin-0.8.0 > instances (with shared notebook storage) > > Hi Sarthak, > > Would you consider store your notebook in cloud, such as s3 in AWS? > > Thanks and Regards, > -Bailin > > From: Sarthak Sharma <sarthak...@media.net> > Reply-To: "users@zeppelin.apache.org" <users@zeppelin.apache.org> > Date: Saturday, March 23, 2019 at 7:44 PM > To: "users@zeppelin.apache.org" <users@zeppelin.apache.org> > Subject: Dynamic updation of notes across multiple Zeppelin-0.8.0 instances > (with shared notebook storage) > > Hi, > > Since there are already many ways of having a shared notebook storage across > multiple zeppelin instances (using nfs, hdfs, etc). > Is there a way of setting up HA for Zeppelin such that if a user updates > notes on a particular instance, the changes get reflected to another user on > some other instance(backend) without having to restart their zeppelin server > (Since currently zeppelin loads all the notes during startup). > > Thanks and Regards > > Sarthak Sharma > > > Site Reliability Engineer, Media.Net > +918002228376 <tel:+918002228376> | sarthak...@media.net > <mailto:sarthak...@media.net> > > <https://urldefense.proofpoint.com/v2/url?u=http-3A__en-2Dgb.facebook.com_people_Sarthak-2DSharma_100006006014244&d=DwMFaQ&c=4ZIZThykDLcoWk-GVjSLmy8-1Cr1I4FWIvbLFebwKgY&r=e506y9nH83Upp3sG65hwe5tYkAEHmDsaZm4J3aW9a-w&m=677aRWui5iwnCcDYhsedYiloLFpRT-UAbU7eI7uKYoo&s=86wjvLRN6mnQL1YjnrDN0aaacQJv2VSNZ8d2mFNetLM&e=> > > <https://urldefense.proofpoint.com/v2/url?u=http-3A__in.linkedin.com_in_sarthaksharma96&d=DwMFaQ&c=4ZIZThykDLcoWk-GVjSLmy8-1Cr1I4FWIvbLFebwKgY&r=e506y9nH83Upp3sG65hwe5tYkAEHmDsaZm4J3aW9a-w&m=677aRWui5iwnCcDYhsedYiloLFpRT-UAbU7eI7uKYoo&s=r6oNvNr-2W7ZtgoYonLXPyXmfMCowI945MDw7ZZWAwQ&e=> > > > > > > This message contains information that may be privileged or confidential and > is the property of the Capgemini Group.
