Re: Zeppelin can let users write Java code?

It's not very well known, but Apache Zeppelin already has one Java interpreter. If you look at Apache Beam one [1] - underneath [2] it has quite generic facilities to interpreter java code, so you can use it for anything, not just Java API of Beam. But Felix's suggestion on using JShell in Java9

Re: [DISCUSS] Reducing default interpreters while building and releasing Zeppelin

Hey guys, great effort! I think people in few other communities will be very happy with it i.e [1] and [2]. Is there an issue that tracks current status or something like that? Does anyone have concrete plans to work on it in this/next release? Sorry if I have missed that out. And please, keep

Re: [VOTE] Release Apache Zeppelin 0.7.0 (RC4)

+1, and thank you for an awesome work Mina! Your persistence in making RCs and incorporating feedback is admirable. Verified: - checksums, signatures + keys for sources and bin-all - bin-all can run all Spark Zeppelin Tutorial in local mode - sources do compile, but only without tests.

Re: [VOTE] Release Apache Zeppelin 0.7.0 (RC1)

Hi Jeff, thank you for the notice, it is a good catch! But the issue that you mention does not have FixFor version assigned - if you want it to part of the release and even conside it as important enough to block the relese vote, could you please update that? This would simplify drastically the

Re: Configuring table format/type detection

Hi Everett, this is a very good question actually. Right now there is not, but it sounds as a great feature, so may be worth filing a JIRA issue. There was a discussion when this feature was contributed [1], [2] and there also is some work on having ability to manually override text\number

Re: Is it possible to run Java code on Zeppelin Notebook?

Good question :) Actually, there is a not very well known yet "hack" (I talked about it a bit on ApacheCon this year) - to run a pure Java paragraph in Apache Zeppelin - you can just use `%beam` interpreter! Beam interpreter uses Beam Java API, so you can leverage it i.e to run WEKA machine

Re: Unable to connect with Spark Interpreter

Hi Jan, this is rather generic error saying that ZeppelinServer somehow could not connect to the interpreter proces on your machine. Could you please share more from logs/* in particular, .out and .log of the Zeppelin server AND zepplein-interpreter-spark*.log - usually this is enough to

Hi Florian, sorry for slow response, I guess the main reason for not much feedback here is that its hard to reproduce the error you describe, as it does not happen reliably even on your local environment. java.lang.NoSuchMethodException: org.apache.spark.io.LZ4CompressionCodec This can be a

Re: build issue, do i need root?

Hi Mohit, no, you do not need to be root in order to build Apache Zeppelin. This looks like zeppelin-web module failed to build web application. This might happen due to different reasons i.e one common is networking issues with bower or npm access. Usually maven build logs list path to npm

Re: show() function not found by the python interpreter after modifying the source code

Hi Alexander, thank you for contributing Matplotlib integration improvements! You are right, it's odd and this is not your text editor's fault - our current Python interpreter implementation is quite early stages and these are artefacts of the way it currently works. Sometimes it does not accept

Hi Kevin, this is very strange indeed. Could you please try to delete ./logs/* restart Zeppelin and try again, and then post 2 full log files, of both zeppelin server and drill interpreter I.e on gist or pastebin and share a link here? This should help to debug the situation. -- Alex On Fri,

Re: Spark/Zeppelin/Cassandra talk

It sounds as a most flexible way, let's try it for 0.6 release and see if it addresses all user needs well. Untill we have GUI for interpreter loading, I feel we also should try our best to make sure netinst usage is documented well, so users on different environments (no internet, corporate
