Shiro auth problem with shiro.ini from Secrets about dcos-zeppelin HOT 4 OPEN

I solved it. I restarted the marathon app with two new env variables :

ZEPPELIN_NOTEBOOK_STORAGE="org.apache.zeppelin.notebook.repo.GitNotebookRepo, org.apache.zeppelin.notebook.repo.zeppelinhub.ZeppelinHubRepo"
ZEPPELINHUB_API_ADDRESS="https://www.zepl.com"

I'm gonna do a pull request to add an env section in the config.jsonand add some stuff in marathon.json.mustache if you don't mind.

Hi @fmarchand , glad you solved it. PRs are always welcome, so by all means go ahead.

This code is ready for this issue #10 ... but ...

When I tried to test the shiro part with the zeppelin-env.sh customization and the placement constraint everything worked except this :

val (df1, df2, df3) = (spark.read.format("csv").option("header", "true").load("hdfs://name-0-node.hdfs.autoip.dcos.thisdcos.directory:9001/kaggle/taxi/yellow_tripdata_2016-01.csv"),
                      spark.read.format("csv").option("header", "true").load("hdfs://name-0-node.hdfs.autoip.dcos.thisdcos.directory:9001/kaggle/taxi/yellow_tripdata_2016-02.csv"),
                      spark.read.format("csv").option("header", "true").load("hdfs://name-0-node.hdfs.autoip.dcos.thisdcos.directory:9001/kaggle/taxi/yellow_tripdata_2016-03.csv"))


val allDfS =  Seq(df1,df2,df3).reduce(_ union _)

I had a NoSuchMethodException in a constructor of the jackson-databind library. After a long time googling that error, I figured out that using spark 2.4 was causing a compatibilty problem. I checked the different versions of jackson from mesosphere image and had to downgrade to 2.4.0-2.2.1-3-hadoop-2.6

This spark image has a spark in the folder /opt/spark/dist whereas more recent images have spark in /opt/spark. Therefore I had to modify SPARK_HOME in Dockerfile and startup.sh. I would suggest to have a branch per package version and propose a PR to mesosphere with multiple version folders.

So the version of the zeppelin package is set to 1.1-0.8.1-2.2.1.

Could you create a branch on your repository so I can do a PR from my forked repository branch to that branch ?

What do you think ?

Hi @fmarchand ,
unfortunately the mesosphere universe is not really designed to handle multiple concurrent versions. And I don't feel comfortable maintaing two versions of the package with different spark versions.
Can you please provide me your code and the complete test you ran? I can try if I can get it working with the current spark version.
