Re: Save Report separately

hi Nirav Patel, Currently zeppelin persists Note as json file，which includes both code and result. You can enable GitNotebookRepo as the bakend storage by define following property in ${ZEPPELIN_HOME}/conf/zeppelin-site.xml。 Restart zeppelin,then you can commit note as a revision, which can be

Sharing RDDS across applications and users

There was a mention of using Zeppelin to share RDDs with many users. From the notes on Zeppelin it appears that this is sharing UI and I am not sure how easy it is going to be changing the result set with different users modifying say sql queries. There is also the idea of caching RDDs with someth

Re: Sharing RDDS across applications and users

Thanks Chanh, Can it share RDDs. Personally I have not used either Alluxio or Ignite. 1. Are there major differences between these two 2. Have you tried Alluxio for sharing Spark RDDs and if so do you have any experience you can kindly share Regards Dr Mich Talebzadeh LinkedIn *

Re: Sharing RDDS across applications and users

thanks Vince. So Ignite uses some hash/in-memory indexing. The question is in practice is there much use case to use these two fabrics for sharing RDDs. Remember all RDBMSs do this through shared memory. In layman's term if I have two independent spark-submit running, can they share result set.

Re: Sharing RDDS across applications and users

I would prefer sharing the spark context and using FAIR scheduler for user concurrency Le 27 oct. 2016 12:48 PM, "Mich Talebzadeh" a écrit : > thanks Vince. > > So Ignite uses some hash/in-memory indexing. > > The question is in practice is there much use case to use these two > fabrics for sha

Re: Sharing RDDS across applications and users

some options: - ignite for spark 1.5, can deep store on cassandra - alluxio for all spark versions, can deep store on hdfs, gluster... ==> these are best for sharing between jobs - shared sparkcontext and fair scheduling, seems to be not thread safe - spark jobserver and namedRDD, CRUD thread saf

Re: Sharing RDDS across applications and users

Hi Just point all users on the same app with a common spark context. For instance akka http receives queries from user and launch concurrent spark SQL queries in different actor thread. The only prerequsite is to launch the different jobs in different threads (like with actors). Be carefull it's no

%knitr still a thing

I tried installing R to get %r and %knitr interpreter in spark but only r is added. I updated at the same time to Zeppelin 0.6.2 using the binary download with all interpreters installed. Is knitr deprecated? my interpreter.json shows / { "class": "org.apache.zeppelin.spark.Spark

Re: Lost connection to the JobManager

Finally got some time to spend on this again. Compiling Flink 1.1.2 with Scala 2.11 and Zeppelin head also with 2.11 has resolved the issue. Not sure why the Flink 1.1.2 binaries compiled with 2.11 didn’t work. Neil > On Oct 20, 2016, at 10:30 AM, Neil Derraugh > wrote: > > I’ve also tried
